The Excelitas/ Heraeus PKS106 is a Photo Ionization Detector (PID) Lamp. This lamp has a 19.6 mm diameter, krypton fill gas and a photon energy of 10.6 eV. The lamp life time at ambient temperature is typically over 3000 hours. It is also know as part number 80017644. 

Applications:

• VOC gas detection
• Gas Chromatography (GC)
• Mass Spectrometry (MS)
• Field monitoring of air and soil
• Emergency first response
• Jar headspace screening
• Leak detection
• Personnel safety in confined spaces
• Portable Gas Sniffers

Heraeus can also manufacture custom design PID lamps, available with a range of components:

• Window materials such as magnesium fluoride, lithium fluoride, sapphire and synthetic silica
• Fill gas options include Hydrogen, Xenon, Krypton, Deuterium, Argon and Mercury Vapor
• DC operated and RF operated versions, with power supplies available for either. In general DC operation is the ideal for fixed-installation instruments such as Gas Chromatographs, where continuous monitoring is required without circuit power constraints. For hand-held detectors, RF versions provide the solution to demands for smaller size and low-power drive circuitry.
• Unique dimensions to fit any instrument.
