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 (full components) automatic monitoring system for volatile organic compounds in ambient air adopts patented ultra-low temperature enrichment method, enabling real-time online enrichment of 116 volatile organic compounds in ambient air (57 PAMS, 47 TO15, and 12 aldehydes and ketones); uses GC-FID-MS analysis method to achieve online analysis of 116 volatile organic compounds.
Instrument Features
• Sampling duration ≥30min, achieving no blind spots in sampling time;
• Adopts patented ultra-low temperature empty tube enrichment technology, with enrichment temperature reaching -190℃ and adjustable;
• Uses low-temperature empty tube technology for water removal, with water removal temperature reaching -60℃ and adjustable;
• Adopts dual-path enrichment and dual-path analysis, no need for central cutting module;
• Can be used for online monitoring of 116 VOCs excluding formaldehyde as required for key regional ambient air VOCs monitoring in 2018;
• Can achieve qualitative and quantitative analysis of 116 substances;
• Can achieve qualitative semi-quantitative analysis of other VOC components beyond the 116 substances;
