Specifications HI93766-25 Range 0.0 to 30.0 mg/L (as N0®¯-N) Resolution 0.1 mg/L Accuracy ±1.0 mg/L or ±3% of reading at 25 °C, whichever is greater Wavelength 410 nm Cuvette Type 13 mm diameter Method Chromotropic Acid Method Method ID #056 # of Vials 25 HI93766-50 Nitrate Pre-dosed Reagent Set 13 mm Vial HI93766-50 is a kit kits of pre-dosed reagents in vials for the determination of Nitrate. There are vials for 50 tests to be used with Hanna’s HI801 and HI802 spectrophotometers. These high-quality reagents are manufactured in our state-ofthe-art facility and are clearly marked with lot number and expiration date for traceability. The method is compliant with ISO 23696 and allows the measure of Nitrates in a very large range: from 0.0 to 30. mg/L NO®- -N. The procedure is very fast (5 minutes), with a representative sample volume (1 mL) and the method has a very little interferences from other substances. The use of 13 mm cuvettes (internal diameter), with a longer optical path than many other vials on the market, ensures accurate absorbance measurements and greater repeatability of results. Signicance and Use Nitrate analysis is crucial in both natural and wastewater management. Elevated nitrate levels can indicate agricultural runo, sewage contamination, or industrial discharge, potentially leading to eutrophication in water bodies. Regular monitoring helps assess water quality, ensure compliance with environmental regulations, and safeguard public health. Accurate nitrate measurement is essential for eective water treatment. Application Environmental monitoring of surface and groundwater, Wastewater, Drinking water quality control, Industrial process water monitoring, Ecological studies of aquatic ecosystems.
