PID - Photoionisation GC Detector
The PID is a GC detector that responds to aromatic and olefinic hydrocarbons in the presence of alkanes and other saturated hydrocarbons.
PID Capabilities
- Unique UV-lamp Window Sweep design minimises fouling of the window surface
- Lampsaver circuit extends lamp lifetime by turning off lamp when not in use
- Non-destructive detector that can directly interface to an ELCD, XSD or FID to form a tandem detector only requiring one detector port
- Detector vent for venting undesirable sample solvents
- Compatible with packed and capillary columns
- Engineered to fit specific GC models
- Easy operation and maintenance
Principal Applications
- USEPA Methods 502.2, 503.1, 602, 8020, 8021
- BTEX, GRO, DRO and VPH
- Aromatics
- Alkenes and Alkynes
- Underground storage tank monitoring
- Waste characterisation
- Air pollution/industrial hygiene
