‍Volatile low boiling and high boiling hydrocarbons are the main components of ozone precursors and one of the main causes of photochemical smog. Ozone precursor analyzer is an instrument used for real-time online monitoring of C6-C12 high boiling point hydrocarbons and C2-C5 low boiling point hydrocarbons in ambient air. The monitored items include 2-methylpentane, n-hexane, benzene, n-hexane, toluene, n-octane, ethylbenzene, meta -, p-xylene, o-xylene, 1,3,5-trimethylbenzene, 1,2,4-trimethylbenzene, 1,2,3-trimethylbenzene, ethane, ethylene, propane, propylene, isobutane, n-butane, isopentane, n-pentane, trans-2-butene, 1-butene, 1,3-butadiene, trans-2-pentene, 1-pentene, isoprene, 2,2,4-trimethylpentane, etc. There are dozens of different boiling points, with a range of up to 300K.

Adopting PID and FID dual detectors to ensure high sensitivity and resolution;

Built in Tenax pre concentration tube or pre concentration system with cooling, thermal analysis or low-temperature thermal analysis, standard capillary pre separation column and analytical column, perfect combination of two chromatography units enables good separation of hydrocarbons in the C2-C12 range;

Adopting a built-in stepper sampling piston as the sampling power system, it can accurately measure the sampling amount and automatically correct the sampling amount according to changes in sampling temperature and pressure, with automatic linearization function;

Compared to pneumatic valves, electronic automatic control ten way valves have more precise and flexible control,

A two-dimensional chromatographic analysis system consisting of dual chromatography columns saves analysis time and extends its service life;

Built in standard industrial computer, capable of automatically controlling various operating parameters of the instrument, and automatically storing and processing data results.

Humanized chromatography workstation, automatically controls various operating parameters of the instrument, automatically saves important parameter information of the instrument at any time, and can trace the cause and location of faults at any time, making it convenient to solve problems;

Multiple data communication protocols, including Ethernet, COM, USB, and analog and digital input/output options;‍
