Some sulfur compounds are known to be not only hazardous but also catalytic poisons. ppb sulfur analysis is conducted by gas chromatography. The Nexis SCD-2030 is a next-generation sulfur chemiluminescence detection system. The dramatically enhanced sensitivity and reliability, the excellent maintainability, and the automation functions, a first for the industry, will improve laboratory productivity.
