EPA 200.7

Environmental Protection Agency – Method 200.7

Laboratory Performance Standard

The EPA 200.7 Method is an approved procedure for measuring the presence and concentration of chemical elements in water matrices solids and biosolids by inductively coupled plasma-atomic emission spectrometry (ICP – AES) evaluating properties such as toxic properties of water.

Target Analysis offers calibration standards, elements for instrument check, and spiking solutions standards.
