ABSTRACT
Frequently it is required not to determine known substances in a sample of water but to screen a sample for the types of organic constituents present. Gas chromatographic and high-performance liquid chromatographic techniques are most valuable in this respect for screening water samples. Other techniques that have found limited application include Fourier transformers proton magnetic resonance spectroscopy, nuclear magnetic resonance spectroscopy. Raman Spectroscopy combined UV-visible fluorescence spectroscopy, cyclic voltammetry, photoelectric spectrometry and gas purging kinetics.
