  • A new 10.0 eV type of Heraeus Photoionisation detector lamps (PID) offer great advantages for determining BTEX VOCs

PID for Selective BTEX Determination

Dec 16 2011 Read 1180 Times

Heraeus Noblelight (Germany), a technology expert in the field of specialty light sources, launches the latest development in its Photoionisation Detector Lamps (PID) range: a 10.0 eV PID lamp which offers increased detection sensitivity in BTEX determination.

“A CaF2 filter is attached onto our standard 10.6 eV PID lamp that permits output of the 10.0 eV line but blocks transmission of the 10.6 eV line. In BTEX determination, the advantages are better selectivity that 10.6eV and increased sensitivity compared to a 9.6 eV (Xenon filled) lamp, because of higher output intensity” explains Russell Fear, PID Product Manager of Heraeus Noblelight Analytics.

Careful selection of materials and attachment of the CaF2 filter window is critical to produce consistent and high performance lamps. This lamp still maintains the high spectral purity and long life that is a feature of Heraeus PID lamps.

Heraeus PID lamps offer an excellent lifetime and proved to last more than 8000 hours. PID lamps are most commonly used in Hand-Held Gas Detectors for VOC detection, gas chromatography (GC), trace gas monitoring and sample ionisation for mass spectrometry.

A detailed Application Note from Heraeus gives more information on the new 10.0 eV PID lamps for BTEX determination.
