Product Introduction

The product complies with HJ 1010-2018 Technical Requirements and Detection Methods for Continuous Monitoring Systems of Volatile Organic Compounds in Ambient Air Using Gas Chromatography.

Application Scope

The instrument is applied in ambient air monitoring areas such as air stations, residential areas, tourist attractions, industrial parks, etc.

System Introduction

The TH-300B/H/L/G (PAMS) online monitoring system for volatile organic compounds in ambient air adopts patented ultra-low temperature enrichment method, enabling real-time online enrichment of 57 PAMS organic compounds in ambient air; uses GC-FID-FID analysis method with central cutting module to achieve online analysis of 57 PAMS compounds.

Instrument Features

•  Sampling duration ≥30min, achieving no blind spots in sampling time;

•  Adopts patented ultra-low temperature empty tube technology for enrichment, with enrichment temperature reaching -190℃ and adjustable;

•  Uses Nafion tube for water removal, with dew point reaching -40℃ and adjustable;

•  Can be used for online monitoring of benzene series compounds;

•  Connects to FPD detector, suitable for online monitoring of sulfides;

•  Connects to ECD detector, suitable for online monitoring of halogenated hydrocarbons.
