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
