Screening with Meaning

Take the lab to the contamination source

Fast Results - Cleaner Sytems

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
