Spectrophotometric method Ingestion-build-58863 where TVOC concentrations in theWhat is BS EN 10200 Spectrophotometric method about? BS EN 10200 is a European standard that discusses the spectrophotometric method for the determination of boron in steels for the chemical analysis of ferrous materials. Spectrophotometric uses a light beam that passes through the sample, and each compound in the solution absorbs or transmits light over a certain wavelength. BS EN 10200 specifies a spectrophotometric method for the determination of
