These reagents follow adaptation of the Standard Methods for the Examination of Water and Wastewater,  18\u003csup\u003eth\u003c\/sup\u003e ed.,  colorimetric method. The reaction between Mg and calmagite indicator causes a violet tint in the sample. A separate sample is treated with EDTA to chelate all calcium and magnesium present. A separate sample is treated with EGTA to chelate any calcium that is present. The difference in color of the two treated samples is determined by a compatible benchtop or portable photometer. The concentration of magnesium is displayed in mg\/L (ppm) as calcium carbonate (CaCO\u003csub\u003e3\u003c\/sub\u003e). These reagents are designed to be used with samples that have an expected range of 0.00 to 2.00 mg\/L magnesium hardness and 0.00 to 4.70 mg\/L total hardness.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eCompatible Photometers Include:\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003eHI83099\u003c\/li\u003e\n\u003cli\u003eHI83200\u003c\/li\u003e\n\u003cli\u003eHI96719\u003c\/li\u003e\n\u003cli\u003eHI96736\u003c\/li\u003e\n\u003cli\u003eHI96741\u003c\/li\u003e\n\u003cli\u003eHI96745\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eSKU\u003c\/td\u003e\n\u003ctd\u003e HI93719-03\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eName\u003c\/td\u003e\n\u003ctd\u003e Magnesium and Total Hardness Reagents (300 tests) - HI93719-03\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage\u003c\/td\u003e\n\u003ctd\u003e Bottles\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eQuantity\u003c\/td\u003e\n\u003ctd\u003e 300 tests\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMethod\u003c\/td\u003e\n\u003ctd\u003e Adaptation of the Standard Methods for the Examination of Water and Wastwater, 18\u003csup\u003eth\u003c\/sup\u003e edition, EDTA colorimetric method.
