Analyze Contaminant in the air |
- Continuous air monitoring
- EPA Method TO17 Adaptation
- No external traps or canisters
- micro thermal desorption trap for sample collection and GC injection
- Rugged micro GC made in steel
- GC backflush to speed analysis
- Backflush to reduce sensor fouling
- Scrubbed ambient air carrier no compressed gases needed
|

| Air FROG Operation | - Collect: Sample air flows over the PC trap and through the GC bypass line
- Analyze: Collected sample is desorbed from PC and injected into GC column
- Identify: GC separates analytes before they reach the PID for sequential detection
- Backflush: Flow reverses through the GC as the last analyte of interest is detected
- Cleaning: Scrubbed air flows over the PID
