The HI93702-03 are high quality reagents that are pre-measured, allowing for users to achieve fast and accurate colorimetric measurements. These reagents follow the bicinchoninate method in which the reaction between copper and the reagent causes a color change in the sample. The intensity of color is determined by a compatible photometer and the copper concentration will be displayed in mg/L (ppm). These reagents are designed to be used with samples that have an expected range of 0.00 to 5.00 mg/L copper.
Package Packets Quantity 300 tests Method Adaptation of EPA approved bicinchoninate method. The reaction between copper and the bicinchoninate reagent causes a purple tint in the sample.
