PID Lamp

Description

• General description: Photoionization detector is suitable to detect and measure the presence of organic vapours. PID lamps emit ultraviolet light to ionize organic vapour molecules. During ionization, free electrons are generated which produce a current proportional to the number of ions present and resulting signal is interpreted as total organic vapour concentration. The most popular PID lamp is the 10.2-eV which has the highest photon flux hence has high sensitivity.[1]
• Application: PID lamp 10.6eV may be used for determination of volatile organic compounds in atmosphere in grab sampling and in situ analysis using Portable Gas Chromatography.[2]
• Features and Benefits: The PID lamp model 108-BTEX offers:33% more enrgizing radiation than the Model 108 lamp, making it more responsive to BTEX moleculesExcellent long term output stablity; less frequent recalibration requiredAfter 3months of continuous operation at 1 ma and 250 degrees Celsius, the BTEX lamp has a higher output than a new and unused Model 108After 6 months of continuous operation at the above conditions, the BTEX lamp has an output better than 50% of its initial output.
