We develop and manufacture enzymes for green analytical chemistry. Our enzymes are reagent grade, manufactured according to strict standards and protocols, ensuring lot-to-lot consistency and ultimate QA/QC. Nitrate, Phosphate, Total N in anything aqueous. Standard Method status for nitrate with the US EPA, ASTM, and others. Our products are great for nutrient management and for soil and water quality analysis at any skill level. Enzyme-based analytical chemistry offers many benefits: Selectivity Enzymes are able to find targets in complex mixtures, reducing sample prep time Sensitivity Enzymes offer low detection limits in complex mixtures Specificity Enzymes react ONLY with the target to be analyzed Safety Enzymes are proteins, meaning non-toxic reagents, no high heat or pressure, heavy metals, or solvents involved Currently, NECi offers Nitrate Reductase in many formats for accurate, reliable, and environmentally responsible nitrate testing. Our Nitrate Reductase is available as bulk reagent, reagent packs (enzyme + co-factor), laboratory test kits, reagent packs for automated laboratory equipment, and easy to use test kits for field testing of any water as well as soil, plant, and dry forage extracts. Our enzymatic nitrate testing method using nitrate reductase is an approved EPA ATP for nitrate in waste water. Laboratories adhering to EPA protocols may seek limited use approval for this method until final approval has been reached. Nitrate analysis by Nitrate Reductase is an approved ASTM Method: D7781. It is available for purchase at http://www.astm.org/Standards/D7781.htm. New in 2020: Total Nitrogen! We are also developing enzymes for testing glycerol, galactose, phosphate, and alcohol, as well as a handheld smartphone-linked photometer for field testing nitrate and phosphate of soil in the field. We are currently seeking Beta testers for these products. Please contact us for more information at (888)-NITRATE or [email protected].
