ABB on-line process gas chromatographs (PGCs) are comprised of two series: The PGC2000 E2 and the PGC5000. The PGC2000 E2 measures discrete hydrocarbons up to C26 in HPI streams. This base PGC is also used in specialty analyzers for measuring fuel Sulfurs and speciates Sulfurs, refinery distillation analysis and temperature programmed analyzer for measuring hydrocarbon streams with a wide range of boiling points. The PGC5000B is used to measure up to C26 in simple applications with a fixed set of features.
