The demand for detection of dangerous materials (dangerous goods) is increasing, because we are paying more and more attention to the dangers of chemicals used in industrial processes and the necessity of personal and environmental protection. Using photoionization detection (PID), volatile organic compounds (VOC) can be detected with extremely high sensitivity.

Photoionization refers to the ionization of molecules caused by the absorption of high-energy photons. The current generated by ionization is proportional to the molecular concentration, so it provides a simple method for quantitative analysis of various compounds. This technique is non-destructive, so it can be used in combination with other detectors for diffusion analysis.

PID lamps are available in two versions: DC operation and RF operation. Generally speaking, DC operation is the first choice for gas chromatography lamps to install instruments, which need continuous monitoring and can support high-voltage power supply. For hand-held detectors, the RF version provides a solution to meet the requirements of smaller size and low power driving.

The advantages of Hershey PID lamp represented by our company:

DC cargo RF-driven PID lamp for hand-held and fixedly installed instruments

Customize PID lamps to match your specific application.

Different filling gases and window materials have photon energy of 9.6-11.8eV, which is more sensitive in gas detection.

High purity window materials output more photons.

Patented getter technology and high-purity filling gas ensure longer service life.

Automatic production ensures stable process and quality.
