VOC 300-B Environmental Air Benzene Series Online Analyzer

Product Introduction

VOC 300-B Environmental Air Benzene Series Online AnalyzerReal time online monitoring of benzene, toluene, and xylene concentrations in ambient air using GC-FID monitoring technology. The analyzer uses pre concentration method to enrich the sample gas, and after thermal desorption, it enters the chromatographic column for separation, and finally enters the FID detector for detection and analysis.

The analyzer detection module is located in the heating zone, which can effectively avoid sample loss. The use of pre separation and valve switching blowback technology can prevent high boiling point components from entering the analysis system, improve the service life of the chromatographic column, and provide a reliable solution for monitoring the concentration of benzene derivatives in ambient air.

Product Features

• Adopting pre concentration method with low detection limit;

• Built in enrichment analysis module, capable of reaching -10 ℃, with a heating rate greater than 40 ℃/s;

• Using electronic pressure flow control technology (EPC, EFC) to control carrier gas, air, and hydrogen, with high accuracy and good repeatability;

• Short analysis cycle and high accuracy;

• FID has the functions of automatic ignition, fire extinguishing, and automatic cut-off of hydrogen gas;

• Independently developed product control software with a simple user interface;

• Automated and intelligent data processing.

application field

• Online monitoring of benzene derivatives at urban air stations;

• Online monitoring of benzene derivatives at the boundary of petrochemical and chemical industrial parks;

• Online monitoring of benzene derivatives in urban roads, airports, ports, and other areas.
