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.

We offer high quality PID lamps manufactured by Andrews Glass Co.

Model 108 is the most commonly used PID lamp. The 0.781 in. (1.98 cm) base diameter is compatible with OI Model 4430, Tracor, and Baseline photoionization detectors.

Model 103C is the original PID lamp (developed by Scientific Services Co). The 1.375 in. (3.49 cm) base diameter is compatible with HNU and SRI detectors.

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.

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 molecules
• Excellent long term output stablity; less frequent recalibration required
• After 3months of continuous operation at 1 ma and 250 degrees Celsius, the BTEX lamp has a higher output than a new and unused Model 108
• After 6 months of continuous operation at the above conditions, the BTEX lamp has an output better than 50% of its initial output.
