- Description
- The U. S. Geological Survey, Central Region, National Water Quality Laboratory (NWQL), has a requirement for an automated, photometric discrete analyzer (DA) for high-demand total nitrogen and total phosphorus assays on automated air-segmented continuous flow analyzer platforms. This DA will provide backup capability for the currently operating NWQL Kone AquaKem 600 DA used primarily for dissolved nutrient (nitrate, nitrite, orthophosphate, and ammonium) analyses. The following are the functional requirements: 1. The DA must be 100% compatible with the currently operating NWQL Kone AquaKem 600 automated DA. 2. The DA must meet the following measurement requirements: have a single channel, dual beam interference filter photometer; have a computer controlled 15-position filter wheel with 13 positions available for a variety of standard and custom filters. The standard filters are 340, 380, 405, 450, 480, 510, 540, 575, 600, 620, 660, 700 and 880 nm. The custom filters are at any wavelength from 340-1050 nm.; have the capability to take a sample blank reading either from the analytical wavelength used for the final determination or from a side wavelength; have reproducibility of 0.005A at 2.0A; have the capability of kinetic and end-point measurements; have the capability of taking kinetic measurements from 15 seconds out to 20 minutes. 3. The DA must meet the following reagent handling requirements: The reagent compartment must be thermally cooled in the range of 4-8 celsius degrees and have the capacity to hold 45 on-board reagents; have the capability to continuously load and unload reagents while the DA is analyzing samples; have the capability of accepting 10-mL, 20-mL, and 60-mL reagent containers; have the capability of adding up to 4 reagents per test; have an integral barcode reader for reagent identification; allow for reagent addition volumes of 2.0 - 225 microliters (uL). 4. The DA must meet the following cuvettes requirements: have a discrete, disposable cuvette segments with linear arrays of 12 reaction/measurement cells; have the capability to dispense and measure all chemistries in individual disposable cells, greatly minimizing cross-contamination and carryover; allow for no reuse of measurement cells; have individual reaction cells that use no more than 250 uL of combined sample and reagent per test; have a large cuvette magazine with cuvette capacity of 150, 12-segment cuvettes (enough for 1800 tests) and that can be loaded at any time without interrupting the operation of the DA; have the ability to operate up to 4 hours without attendance. 5. The DA must meet the following sample handling requirements: have an integrated internal barcode reader to provide recognition of sample container types, and automatic linkage of sample identifier barcode labels with test requests through a Laboratory Information Management System (LIMS) interface; have 14-position sample segments with the ability to accept 0.5-mL and 2.0-mL, and 4-mL sample cups, and 5-mL, 6.5-mL, and 10-mL sample tubes; provide dispensed sample volumes ranging from 1.0 uL to 120 uL.; provide automatic or operator requested dilutions up to 1+119 (1 part sample + 119 parts of diluent by volume; perform up to 600 tests an hour. 6. The DA must meeting the following dispensing requirements: have separate syringe-pump based systems for sample and reagent dispensing operations; use precision syringes driven by micro-stepper motors for all sample or reagent dispensing operations. 7. The DA must meet the following dilutions requirements: have the capability for sample pre-analysis dilution; have the capability of same post-analysis dilutions up to 1:119, ensuring that overrange samples are automatically diluted and re-run without user intervention; 8 The DA must meet the following quality control requirements: have 19 available positions for individual QC samples ("controls") on a plate integral to but separate from the sample container segment carousel. 9. The DA must meet the following calibrations requirements: have the capability to run separate calibration standards or to prepare serially diluted calibrators; provide for multiple analyses of the same calibrators to prepare a calibration curve; perform dilutions that range up to 1+119; have 20 available positions for individual calibrators in the sample compartment which are separate from positions on sample segments. 10. The DA must meet the following reaction incubation requirements: have a reaction incubator thermostatted at 37 Celsius degrees to facilitate various chemical analyses; have a 20-position incubator that has the capability of heating 240 reaction cells simultaneously. 11. The DA must meet the following data management requirements: include software that is compatible with Windows XP Professional?; include software that is bi-direction in its communication with the Laboratory Management Information System (LMIS) and have the capability to report test results to the LMIS. 12. The DA must include 12-month Preventative Maintenance kits which each include at least 2 dispensing needles, 2 syringes, 2 mixing paddles, diluent and wash tubing, drain and waste tubing, and peristaltic pump tubing. 13. The DA must have demonstrated performance to meet NWQL requirements for high-demand total nitrogen and total phosphorus assays. 14. The DA must be shipped and installed within one month from the date of purchase. 15. The DA must be installed and calibrated by factory trained personnel. 16. The DA must be warranted for one year from the date of installation. 17. The DA shall include a preventative maintenance visit 6 months after installation which shall include changing all parts contained in preventative maintenance kits and the running of performance evaluation mixture to ensure proper operation. 16. On-site service must be available. The suggested DA for high-demand total nitrogen and total phosphorus assays is Kone AquaKem 600 automated discrete analyzer. The sole authorized distributor of this DA is Environmental Sample Technology, Inc. Based on the information available at this time, and in accordance with 41 U.S.C. 253(C)(1), implemented by FAR 6.302-1, the Government considers the DA specified as a sole source from Environmental Sample Technology, Inc., 503 Commercial Dr., Fairfield, OH 45014, and proposes to negotiate a contract with that firm. However, should additional sources be identified, they will be considered. Firms that think they can furnish the required DA or its functional equivalent (based upon the criteria specified herein) are invited to submit in writing an affirmative response to this announcement. An affirmative response would include literature, brochures, and such other materials, which correspond to the required DA stated herein. This information will be evaluated and used to determine if competitive opportunities exist. Since no solicitation document exists, requests for such document without accompanying information will be considered non-responsive to this request and will not be considered further. This notice may represent the Government's only official notice of this procurement. See Numbered Notes 1 and 22.
