PID (Photo Ionisation Detector) Lamps

Demand for hazardous material (hazmat) monitoring is ever increasing, as we become more aware of the dangers of chemicals used in industrial processes and the need for personal and environmental protection.

One important set of materials — Volatile Organic Compounds (VOCs) — can be detected with very high sensitivity using Photoionisation Detection (PID).

Photoionisation is the term for the absorption of high energy photons by a molecule which results in ionisation of that molecule. The current created by ionisation is proportional to the concentration of the molecule, so this provides a simple method for quantitative analysis of a variety of compounds.

The technique is non destructive so can be used in conjunction with other detectors for extending the analysis. Photons will only ionise molecules with an ionisation potential less than the photon energy. Our PID lamps are available in a range of energies to suit compound selection.
