• Instrument touch screen interface does not require PC for operation
• Local data storage, front panel USB port, and remote access for data retrieval
• Additional functionality via optional s/w plugins (i.e. valve multiplexer)
• Digital lamp and detector electronics w/ remote control and display

• Low dead-volume valve assemblies with inert PEEK surfaces
• Integrated sample and breakthrough trap assessment with option for single or combined heating to provide measurement and QA assessment options
• Constant power heater control insures consistent temperature over heater life
• Unique design isolates analytical cartridge from complex natural gas matrix; the cartridge is only exposed to carrier gas for optimal performance and robustness
