Auto-Calibration/Dilutor Option
Auto-Calibration/Dilutor Option
Allows self-calibration in the field Built into the unit Reduces cost of operation
Less expensive gas standards at ppb levels
Allows for simpler field maintenanceRecalibration of the detector is easy!Multi-point calibration improves accuracy
and dynamic range

How Does It WorkHow Does It Work
Sample is introduced into the unit
Pre-concentrator to provide greatest sensitivity
Pre-concentrator is heated to produce a plug of gas on analytical column
Gas of interest is separated from background gases on GC column
After a reproducible period of time, gas of interest is detected with solid state detector
