PHOTO-IONIZATION DETECTION (PID) TECHNOLOGY

DETECTION (PID) TECHNOLOGY APPLICATION NOTE TSI-147 How does a PID work? TSI measures Volatile Organic Compounds (VOCs) in air by Photo-Ionization Detection (PID). A PID uses an ultraviolet (UV) light source to break down VOCs in the air into positive and negative ions. The PID then detects or measures the charge of the ionized gas, with the charge being a function of the …

use Photo-Ionization Detection (PID) technology. Each PID sensor is equipped with a UV lamp which emits high energy photons onto a sample of ambient air drawn into the sensor chamber (see diagram below). When hit with this UV light, most VOC molecules, with the exception of low molecular weight VOC’s, will break up into free electrons and positively charged ions, a process called ionization ...

PID SENSORS FOR VOC TECHNICAL DATA LIFESPAN …

Currently, our devices use Alphasense PID-A1 Photoionization detector. madur proposes two stock ranges of VOC detection - 100 ppm and 1000 ppm, both with resolution of 1 ppm. However, as the PID-A1 has a linear dynamic range from 100-ppb to 6,000-ppm (Isobutylene), it can be calibrated for a different range to suit our customer’s needs. On a special demand we are ready to provide sensor ...

PID Sensors | Photo-ionisation Detectors | Alphasense

Photo-ionisation Detectors (PID) With a PID, the sample gas is exposed to deep ultraviolet light. The emitted light ionises targeted gases and they are then detected by the PID electronics and reported as a concentration (ppb or ppm). PIDs can measure Volatile Organic Compounds (VOCs) to very low concentrations. Considered the gold standard for VOC measurement, Alphasense PIDs are compact …
