Oxidant Reagent (non-corrosive)
with NIST Traceable Calibrators US and Foreign Patents Pending
Usage: To detect adulteration in urine by the quantitative determination of Oxidants to include but not
limited to nitrite, chromate, bleach, bromine, halogens and other oxidatively active substances in urine.
This assay is not for use in diagnosing disease or illness to effect treatment, and/or cure; it is for
Forensic / Toxicology use only. Oxidants include nitrite, chromate, bleach, etc. This is the only noncorrosive
nitrite reagent on the market. This reagent will not destroy your instruments, refrigerators or
metal parts.
Method: Colorimetric : Endpoint.
Principle: When an oxidizing agent is present in a urine sample, it reacts with the Oxidant reagent
containing a substituted benzene compound and forms a color complex, readable at 660 nm.
Storage and Stability: Store at 2-10° C. The reagent is stable until expiration date on the container.
Specimen Collection & Preparation: The Oxidant reagent may be used on any freshly voided urine
specimen or urine collected under special conditions, such as first-morning specimens and post-prandial
urine. The urine, collected in a clean container, should be tested as soon as possible (do not centrifuge
or use preservatives). If testing cannot be performed within one hour after collection, the specimen
should be refrigerated at 2-10° C immediately and returned to room temperature before testing. Mix
specimen thoroughly before testing.
Regulatory Agencies Suggested Cutoffs for General Oxidant Assays: 50 mcg/mL Chromate for General Oxidant Assays and for the
Chromate assay. If screening for Nitrites only a cutoff calibrator of 200 mcg/mL Nitrite for General Oxidant Assay and for the Nitrite assay
the use of 500 mcg/mL cutoff calibrator is used. Federal Register /Vol. 73, No. 228 /Tuesday, November 25, 2008.
