New method simplifies measurement of sulfur compounds in waste streams.
Scientists developed a simple method to measure sulfur compounds in liquids and gases. They used headspace chromatography to analyze these compounds in a salty liquid with pH 8.4. By adding an acetate buffer, they improved the detection of specific sulfur compounds. The method was accurate within a certain range for both liquids and gases. Gas standards could be used to calibrate the liquid phase, saving time and avoiding unstable liquid standards. This method was successful in analyzing sulfur compounds in natural gas desulfurization plants and other waste streams.
