Online chromatograph for the continuous analysis of BTEX (Benzene, Toluene, Ethylbenzene, Xylene) by use of the PID detection principle (photoionization detector) using nitrogen as a carrier gas for the measure at ppb and ppt concentrations in air, soil, or water. Ideal BTEX analysis for up to 8 compounds for monitoring in urban and non-urban areas, defense perimeters in refineries, indoor and outdoor air control, and industrial hygiene, among others:
