Sensitive and robust sensor
A high-energy UV light emitting photo ionization detector (PID) of 10.0 eV or 10.6 eV ionizes groups of molecules. As a result, the sensitivity of a PID goes down to very low detection limits in the ppb range. Moreover, the sensor is be very robust with little maintenance needed and therefore ideal for portable applications. However, the sensor alone cannot detect selective target compounds since it ionizes molecules of different compounds collectively.
The physical separation of gas chromatography is improved by a powerful algorithm which mathematically segregates overlapping signals of compounds with similar volatility. This so called deconvolution is performed by proprietary software in the background and close to real-time.
