Trace sulfur - and -aromatics - component analyzer is a device that can analyze the levels of aromatic compounds and sulfur in various kinds of gaseous - samples. It is designed as per the PerkinElmer CLarus - Gas Chromatograph which has pneumatic control which can be either programmable or manually operated. It usually comes with two channels equipped with polar or - sulfur capillary - column and gas sampling - valve based on channel. It can be used for analyzing, COS, SO2, H2S, sulfides, mercaptans, benzene, xylenes, toluene, compounds of aromatic sulfur, ethyl benzene and so on. The features of the device can also vary as per the photo - Ionization - detector and sulfur - chemiluminescence - detector used in it.
