Recent Advances in Applications of the Microcoulometric Titrating System
Since the introduction of microcoulometric gas chromatography in 1960, considerable effort has been expended in the development of new fields of use for this unique analytical system. The instrumentation was used originally as a gas chromatographic detector and applied to the area of pesticide residue analysis because of the system’s specific response to chlorinated and sulfur-containing organic compounds. In recent years, however, use of this versatile analyzer has been extended to include applications in the chemical, petroleum, natural gas, and steel industries. Current development effort has resulted in increasing the capability of the microcoulometric titrating system to include specific response to volatile nitrogen-containing compounds in addition to sulfur and halogen analysis. Continuing investigation indicates the possibility for specific carbon and phosphorus detection as well as selective response to certain classes of organic compounds.
