HomeMy WebLinkAboutR-2024-104 Resolution authorizing the Sole Source purchase of an Ion Chromatograph from Metrohm USA, Inc. for the City of Yakima Wastewater Treatment Plant Laboratory RESOLUTION NO. R-2024-104
A RESOLUTION authorizing the sole source purchase of an Ion Chromatograph from
Metrohm USA, Inc. for the City of Yakima Wastewater Treatment Plant
Laboratory.
WHEREAS, Article VI, Section 6 of the City of Yakima Charter and the Yakima Municipal
Code Chapter 1.80 generally requires that purchases over $50,000 be accomplished by
competitive bidding, subject to certain exceptions; and
WHEREAS, the law recognized a "sole source" exception for these competitive bid
requirements when, due to unique specifications and requirements, it would be futile to utilize
competitive bidding; and
WHEREAS, the treatment plant is required under NPDES Permit WA0024023 with the
Department of Ecology to monitor nutrients in wastewater samples; and
WHEREAS, the laboratory's existing ion chromatograph that is used to monitor
wastewater nutrients has reached the end of its service life and requires replacement; and
WHEREAS, the Purchasing Division advertised a "Notice of Intent to Sole Source" in the
Yakima Herald-Republic on 4/23/24 and 4/25/24 and no vendor came forth to compete for this
equipment; and
WHEREAS, a web search was conducted for other vendors that could provide the unique
combination of hardware and software features of high data quality, usability, and cost-efficiency
of the Metrohm instrument, in which there were none; and
WHEREAS, pursuant to RCW 39.04.280 (1)(a), any requirements for competitive bidding
for the acquisition of the above-described instrument is hereby waived by adoption of this
Resolution, due to the fact that:
(a) Although there are other manufactures of nutrient analysis instruments on the market,
it is documented that Metrohm is the only manufacturer that provides in-line ultra-
filtration and an anion chemical suppressor, which is required by the wastewater
laboratory because:
1) the in-line ultra-filtration unit uses filter paper at a lower cost versus hand-filtration
through 0.45 urn filters and column traps that require replacement at a higher
frequency; and
2) the design of the chemical suppressor utilizes as much as 4 times less volume of
eluent and requires no replacement of costly consumable cartridges; and
(b) The Metrohm instrument comes with easy-to-use software that is familiar and requires
no further training costs; and
(c) The Metrohm instrument uses a chemical anion suppressor that lasts 3-5 years with
free replacement under the 10-year warranty, instead of competitors' electrolytic anion
suppressor that lasts 6 months to a year; and
1
(d) The Metrohm instrument comes with sequential suppression, which further lowers
detection limits and provides a 30% increase in sensitivity; and
(e) The instrument is clearly and legitimately limited to a sole source of supply; and
WHEREAS, Metrohm USA, Inc. has agreed to provide the instrument, autosampler, and
a 2-year total service contract for $57,450 as included in the attached quotation; and
WHEREAS, the City Council finds that it is in the best interests of the City to approve the
purchase of the replacement Ion Chromatograph instrument described above, and that such
approval will enable the City to continue to meet regulatory permit requirements for wastewater
monitoring; now, therefore
BE IT RESOLVED BY THE CITY COUNCIL OF THE CITY OF YAKIMA:
Section 1. The City Council finds and determines that the purchase of a replacement
Ion Chromatograph instrument is clearly and legitimately limited to a sole source of supply,
justifying the waiver of competitive bidding in this acquisition, which bidding requirements are
hereby waived.
Section 2. The purchase and installation of the Ion Chromatograph instrument, as
described above, for an amount not to exceed $57,450. is approved.
Section 3. The City Manager, or his designee, is hereby authorized to accomplish the
purchase of such instrumentation, and to execute any and all documentation to accomplish such
purchase.
ADOPTED BY THE CITY COUNCIL this 4th day of June, 2024.

Susan Knotts,Buyer II,signing in place of the Purchasing Manager per direction of Assistant City Manager.
The WWTP Lab conducted a web search for equipment that could provide full resolution of fluoride, chloride, nitrite,
nitrate, ortho-phosphate in EPA Method 300.0 for required nutrient analysis. A search on Lab Compare for"Ion
Chromatography Instrument" yielded 12 products, from three companies, 1) Metrohm USA, 2) Thermo Fisher Scientific,
and 3) Shimadzu Instruments.
After reviewing each of the instrument's specifications, the Metrohm Ion Chromatograph is the only instrument that
provides the unique combination of in-line ultra-filtration and an anion chemical suppressor, which uses four times less
eluent and requires no replacement of costly consumable cartridges.
The competitors require hand-filtration of samples through 0.45 um syringe filters and replacement of consumable
column traps. Metrohm's chemical anion suppressor is much more cost effective to use because it lasts 3-5 years with
free replacement under the 10-warranty, whereas the competitors' electrolytic anion suppressor only lasts 6 months to
a year. In addition, the Metrohm instrument also comes with a sequential suppression which further lowers detection
limits and provides a 30% increase in sensitivity. The Metrohm instrument also comes with easy-to-use software that is
familiar, which eliminates further training cost, and parts from the previous ion chromatograph's autosampler would be
available as a back-up, if necessary.

2. Eligible reasons for sole source - Unique design: Requires unique features that are
essential, aesthetic requirements, or not possible to match to existing design or equipment.
Describe.
Metrohm offers unique leading technology advances which include, but are not limited to, an
anion chemical suppressor and in-line ultra-filtration. Though competitors offer chemical
suppression,as much as 4 times the volume of eluent is required, adding to the costs of daily
operation. Metrohm's anion chemical suppressor consists of 3-identical chambers that rotate, a
unique design feature that requires much smaller amounts of eluent to be used.
Metrohm is the only vendor that offers in-line ultra-filtration with a paper filter that can last
anywhere from 100-300 samples before requiring replacement. The competitor uses column
traps that require replacement.
The chemical suppressor has a 10 year warranty, a specification unique to Metrohm. The
Metrohm system's versatile design is more than capable of meeting our current needs while
offering the option of expanding analyses in the future.
Other:
The competitors' electrolytic anion suppressor''' does not last as long(6 months-1 year) as
Metrohm's chemical anion suppressor(3-5 years, free under 10 year warranty). In our
experience, the 881 chemical anion suppressor lasted over 10 years, without needing
replacement. The competitors require costly cartridges for the eluent and suppressor that need to
be changed for maintenance. The cost of consumables within the first year from Thermo Fisher
Dionex (Thermo) is—$2,000-$3,000 for replacement of the suppressor, column, and column
traps. Column traps are not necessary for Metrohm because of their highly rated ultra-filtration
technology (—$0.06 to $0.07 per sample).
The 919 Autosampler used with the old 881 system, can be used as a spare with the new 930
system or provide spare parts, if necessary. Also, any of the repair equipment and consumables
(i.e., filters, sample line tubing, etc.) can be utilized with the new system, providing further
savings in parts. Metrohm's consumables (i.e., standards, sample tubes, filters, etc.) are
available through other vendors and do not require purchase through their company. Most of the
consumables the competitors require are "locked-out" and only available for purchase through
their company.
The Metrohm Magic Net software has been user friendly compared to references using Thermo
software. In our experience, Metrohm's customer service has excellent and prompt. References
have reported poor customer service and long wait times from Thermo.
3. Is this product/service available only through one vendor? Yes.
A web search on Lab Compare for `Ion Chromatography Instrument' yields 12 products from 3
vendors: Metrohm USA, Thermo Fisher Scientific, and Shimadzu3. Metrohm USA Inc.
(Metrohm) offers the latest technology advances which include, but are not limited to, an anion
chemical suppressor with a 10-year warranty, in-line ultra-filtration, and the ability to switch
quickly between anion and other types of ion analyses, if desired.
Though competitors offer chemical suppression, Metrohm's anion chemical suppressor consists
of 3-identical chambers that rotate, a unique design feature that requires much smaller amounts
of eluent(i.e., about 4 times less)to be used. The competitors require hand-filtration through
0.45um filters4 and column traps that need to be replaced at a much higher cost and frequency
than Metrohm's ultra-filtration filter paper that can last from 100-300 samples before replacing.
5. Why is this a sole source vendor?
The 881 Metrohm Ion Chromatograph (IC) that was used daily for routine required nutrient
analysis in the Wastewater Lab stopped
the working
g beyond a repair
in
replaced.February 2024. Required
testing is being sent to contractsystem
The repair estimate for the 881 service call & parts is a blanket dollar amount of$8,0
00. Even if
repair costs are less, the end of the service agreement support, where Metrohm is no longer
obligated to provide parts for the 881, has been reached. Thus, it is more cost effective to
upgrade.
The 881 Metrohm IC was purchased in 2013 via Sole Source. The unique design features and
the fact that Metrohm has provided excellent technical support for over 10 years has lead us to
upgrade via Sole Source again to the 930 Compact 9119 Autosampler,available as a back-up and for spare
have the 881 components, specifically
parts.
6. What efforts were made to assure the City if receiving the lowest or best price possible?
Several efforts were made during negotiation of the quote to assure that the City is receiving the
lowest price possible. Because we are returning customers, Metrohm has offered a 10%total
discount and an additional 5% savings in comps for standards and consumables. Additionally,
free shipping and handling has been applied to the quote, if the purchase order is received before
8/30/2024.
In addition, since we are familiar with Metrohm's 881 IC system and the Magic Net Software,
we are able to forgo the 930 IC Flex training at a cost of$2,700. We are also able to save
another$2,000 by utilizing the same ultra-filtration apparatus and additional costs by using the
existing Windows 10 computer system.

Additional Information
Here is some information for side by side comparisons of specifications as mentioned in the justification:
1) Metrohm Ultra filtration technology:
The inline filter system Metrohm uses is actually called inline Ultrafiltration. The reason it is called that
is because the pore size of the membranes are very small (0.2 um). For this reason,filter caps and
syringes aren't required. It doesn't get clogged because of the flow mechanism. 25-40% percent of the
sample is pulled up through the filtration membrane and to the IC. The other 60-75%is pulled to waste.
The constant flow between the two channels is what prevents a filter cake from forming. The
ultrafiltration cell is not a consumable and doesn't need to be changed. The membranes generally need
to be changed every 100-200 injections, depending on the sample type. The cost to filter one sample is
about$0.06 to$0.07. To see an animation of the ultrafiltration technology,visit:

Pretreating Samples
Analyze rainwater, drinking water,and air particulate leach solutions directly with no sample preparation
(other than filtering and possibly diluting).
Filter groundwater and wastewater samples through 0.45 µm filters before injection, unless samples were
filtered after collection.
Before injection,pretreat samples that may contain high concentrations of interfering substances by
putting them through Thermo ScientificTM DionexTM OnGuardTM cartridges. Refer to Installation and
Troubleshooting Guide for OnGuard Cartridges(Document No.032943)for instructions.
2) The IC Suppressor: Chemical (Metrohm)versus Electrolytic(Thermo Fisher,Shimadzu)Suppression
With Ion Chromatography,the instrument measures ions(chemical compounds with a positive or
negative charge)with a conductivity detector; however these ions are in a solution of charged ions
called eluent(a carrier fluid). Thus, in order to measure the ions of interest, the eluent needs to be
suppressed—exchanged with ions of a lower conductivity(chemical suppression)or converted to
neutral or non-charged compounds(electrolytic suppression). There are two types of suppression:
Chemical and Electrolytic.

Finally, to give an even better description of Metrohm's patented suppressor technology, here is an
animation:
https://www.bing.com/videos/riverview/relatedvideo?q=metrohm+suppressor&mid=9F4B1903BF7278
F425599 F4B 1903 B F7278F42559&FORM=VI R E
The above animation shows the 4-step process that is described below:
1. The analytes and mobile phase coming from the column are acidified via cation exchange in this
chamber,as you see in this case, losing a Na+ion and gaining an H+ion.The mobile phase here
is converting from bicarb/carb buffer over to carbonic acid, H2CO3.This acid has very low
conductivity,so S/N ratio is vastly improved with this step.
2. The chamber has been used for suppression,so it now needs to be regenerated offline from the
chromatography workflow. It is introduced to a line of 500 mM sulfuric acid,which replaces all
of the active sites on the cation exchanger with protons, H+.You now have a protonated cation
exchanged amidst a free flowing solution of sulfuric acid.
3. This next step rinses all of the non-bound acid in the chamber, using a healthy dose of DI water.
Once thoroughly flushed,the chamber is in the regenerated and rinsed state, ready for
suppression again.
4. As there are three identical chambers, at step 4,you are basically back to the beginning of step
1, ready to suppress another anion sample.And the process goes on and on, allowing a stable
baseline to not only go down to 1-4 mS/cm, but STAY there over time.
Thermo Fisher cartridge-based eluent generation and suppression
The ions required for eluent generation as well as suppression are generated by the electrolysis of water
(breakdown of H2O into H+and OH-with electric current).This technology is known as Reagent Free Ion
Chromatography, RFIC. However,the cartridges themselves are considered HAZMAT once they hit less
than 50%capacity and must be disposed of.
Generation:
Thermo KOH cartridges claim to be reagent free because the reaction is DI Water+ Proprietary EGC.
Metrohm does not offer cartridge-based eluent generation because they found it can lead to'dirty
chromatography' and wanted to make sure customers acquire consistently reproducible results without
risking the change of contamination entering the IC from recycled eluent.
Suppression:
Metrohm's chemical suppressor(using a Metrohm Suppressor Module (MSM) Rotor) allows for the
exchange of ions of lower conductivity so that the conductivity of the ions of interest are enhanced. If
the suppressor needs to be replaced (every 3-5 years or 6000 samples) it will be covered under the 10-
year warranty.
The Thermo cartridge-based suppressor(electrolytic)does not last as long as the chemical suppressor,
the MSM rotor inside of a Metrohm IC.Thermo Suppression cartridges are a consumable,costing nearly
as much as column and guard column consumable costs. References state they have to replace the
suppressor every 6 month—1 year at a cost of$1620.This is about 1000-3000 samples,depending on
how fast and how many samples are ran in a work day.

BUSINESS OF THE CITY COUNCIL
YAKIMA, WASHINGTON
AGENDA STATEMENT
Item No. 7.F.
For Meeting of: June 4, 2024
ITEM TITLE: Resolution authorizing the Sole Source purchase of an Ion
Chromatograph from Metrohm USA, Inc. for the City of Yakima
Wastewater Treatment Plant Laboratory
SUBMITTED BY: Susan Knotts, Buyer II, Purchasing
*Mike Price, Wastewater Manager
SUMMARY EXPLANATION:
The WWTP Lab conducted a web search for equipment capable of providing full resolution of fluoride,
chloride, nitrite, nitrate, ortho-phosphate in EPA Method 300.0 for required nutrient analysis. A search
on Lab Compare for"Ion Chromatography Instrument" yielded 12 possible products, from three
companies, 1) Metrohm USA, 2) Thermo Fisher Scientific, and 3) Shimadzu Instruments.
Upon reviewing the specifications for each of the instruments, it was determined that the Metrohm Ion
Chromatograph is the only instrument that provides the unique combination of in-line ultra-filtration and
an anion chemical suppressor, which uses four times less eluent and requires no replacement of costly
consumable cartridges. The competitors require hand-filtration of samples through 0.45 um syringe filters
and replacement of consumable column traps. The Metrohm intrument's chemical anion suppressor is
significantly more cost effective to use because it lasts 3-5 years with free replacement under the 10-
warranty, whereas the competitors' electrolytic anion suppressor only last 6 months to a year. In
addition, the Metrohm instrument also comes with a sequential suppression which further lowers
detection limits and provides a 30°/o increase in sensitivity. The Metrohm instrument also comes with
intuitive software that is familiar, which eliminates further training cost, and as it replaces an instrument
from the same manufacturer, some parts from the previous ion chromatograph's autosampler would be
available as a back-up, if necessary.
ITEM BUDGETED: Yes
STRATEGIC PRIORITY: Public Safety
RECOMMENDATION: Adopt Resolution.
