Luminometer routine reagents are a range of reagents for measuring the concentration of different chemical substances, designed for a variety of analytical needs. These reagents are able to react with target chemicals in a photometer to provide accurate measurements. Different types of reagents are suitable for the determination of ammonia nitrogen, residual chlorine, total chlorine, copper, nitrite, manganese, aluminum, iodine, calcium hardness, magnesium hardness, iron, hexavalent chromium, nickel and nitrate and other chemical substances from low to high concentrations, and each reagent provides 100 tests (except for some models such as high concentration ammonia nitrogen reagents can reach 300 times). These reagents are widely used in water analysis and environmental monitoring to ensure accurate and reliable measurement of chemical concentrations in a wide range of liquid samples.
HI93719-01 is a pre-measured, high-quality reagent that allows users to achieve fast and accurate colorimetric measurements. These reagents follow the adaptation of the Standard Methods for Water and Wastewater Inspection, 18th Edition. Colorimetry. The reaction between the Mg and the calcite indicator resulted in a purple tint in the sample. Separate samples are treated with EDTA to chelate all present calcium and magnesium. Treat individual samples with EDTA to chelate any calcium present. The color difference between the two processed samples is determined by a compatible benchtop or Portable Photometer. The concentration of magnesium is shown in milligrams per liter (ppm) as calcium carbonate (CaCO3). These reagents are designed for samples with an expected range of 0.00 to 2.00 mg/L magnesium hardness and 0.00 to 4.70 mg/L total hardness.
