Chemetrics I-2016, Photometer Single Analyte Meter (SAM) Kit

SAMs (Single Analyte Meters): Value and Convenience Single Analyte Meters (SAMs) provide unprecedented economy, simplicity, and accuracy for dedicated photometers. SAMs provide results equivalent to other meters and probes costing much more. SAM (Single-Analyte Photometer) Kit comes in a plastic case and contains everything needed to perform 30 tests: K-5543 Vacu-vials Kit, SAM Photometer, 2 AA batteries, and instructions. The Ferric Thiocyanate Method The ferric thiocyanate method consists of ammonium thiocyanate and ferrous iron in acid solution. Hydrogen peroxide oxidizes ferrous iron to the ferric state, resulting in the formation of a red thiocyanate complex. Chlorine will not interfere with this method. Ferric iron will interfere. Results are expressed as ppm (mg/L) H2 O2 .
