B -- FIELD TESTS FOR MEASURING CHLORINE DIOXIDE SOL FSIS-3-W-95 DUE 031795 POC Contact Point, Julie Adams, (202)720-9891 The Department of Agriculture, Food Safety and Inspection Service (FSIS), intends to review field tests for measuring chlorine dioxide in water in the ranges of 0-5 ppm and 0-50 ppm. In the low range, the best tests should be able to determine chlorine dioxide in water that is colored with heme and that contains significant amounts of suspended particulate and organic matter. Tests will be reviewed to determine the usefulness of various generic chemistries and formats, not to select a particular test kit. A laboratory review will examine such parameters as ruggedness, exactness and reliability of results, cost, and ease of use. Test results will be compared against chlorine dioxide results determined by amperometric titration in the same sample. Respondents should be aware that the selected chemistry(s) and format(s) may be published in a proposed rule governing utesting for chlorine dioxide in meat plants. No viable techniques should be excluded from this review. This request is for information and planning purposes only, not a request for proposals and does not commit the government to pay for preparation or demonstration costs. The government does not intend to award contract(s) based on the information received. Vendors are reminded that only the Contracting Officer has the authority to commit government funds. Interested vendors with a field useable test for chlorine dioxide that can perform within these concentration ranges may submit information to the Contracting Office at the above address. Responses shall be submitted by close of business March 17, 1995. (0053)
