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 (ODS/HFS) online monitoring system for volatile organic compounds in ambient air adopts patented ultra-low temperature enrichment method, enabling real-time online enrichment of 36 ozone-depleting substances (ODS/HFC compounds) in ambient air; uses GC-MS analysis method to achieve online analysis of 36 ODS/HFS 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 low-temperature empty tube technology for water removal, with water removal temperature reaching -60℃ and adjustable;
• Negative pressure sampling to avoid pollution and condensate water caused by positive pressure sampling pump;
• Very low detection limit, with detection limits for most substances below 0.3 ppt;
• High precision, with RSD ≤5% for most substances (50 ppt).
