Heraeus has many years of exrience in providing DC and RF driven PID lamps to leading instrument manufacturers. Applications include gas chromatography, portable gas sniffers and sample ionisation for mass sctrometry. The Heraeus engineering team works closely with instrument development engineers to design unique lamps matched to the instrument. Miniature PID lamps （P_R-6 series） for very compact handheld applications, e.g. in gas monitoring, are a Heraeus sciality.

 

           different gas fills （e.g. Xenon, Krypton, Deuterium, Argon）

           very high gas fill purity for long lamp lifetime

           different window materials with different cut-off wavelengths

           high purity window material for better transmission

           DC or RF （electromagnetic field） driven lamps

           unique lamp designs and dimensions to fit any instrument 

 

 

Heraeus photoionisation lamps are available with a variety of gas fills including argon, krypton, xenon and deuterium gases. When used with the windows detailed below, outputs are equivalent to the photon energies quoted. 

 

 

 

Heraeus PID lamps are available with magnesium fluoride, lithium fluoride, sapphire and synthetic silica windows. Magnesium fluoride is the most common window material, providing excellent deep ultraviolet transmission with reasonable lifetime. Heraeus’ unique processing technique allows the use of a thinner MgF₂ window improving transmission and therefore improving life due to a reduction of the density of light absorbing colour centres.
