To meet the need for compact gas detection instruments, Heraeus Noblelight now presents a complete range of photoionisation (PID) lamps for gas chromatography and portable gas analysis
Gas detection is a growing market driven by increased environmental regulations.
In the EU, for example, monitoring benzene in ambient air is mandatory.
To meet the need for compact gas detection instruments, Heraeus Noblelight now presents a complete range of photoionisation lamps for gas chromatography and portable gas analysis.
Both RF and DC energised lamps are available.
Heraeus specialises in lamps that fulfil the needs of online instruments and portable analysers: small dimensions, high robustness and flexibility to be adapted to the instrument's operating requirements.
Prototype PID lamps in a customer-specific design can be supplied in as a short time as five weeks by the Heraeus PID competence centre in Cambridge, UK.
Photoionisation gas chromatographs have seen widespread success, eg in the detection of benzene and other aromatic hydrocarbons.
They offer a high specific sensitivity, start up fast and are easy to operate.
This is important as it enables the instruments to be operated by field technicians with limited specialist knowledge.
With adequate software and automatic calibration, the PID lamps can work for several years before needing exchange.
