The PhotoMate light source uses a Krypton lamp which emits photons at 10.0 and 10.6 eV. Krypton was carefully selected because these photon energies, while being sufficient to ionize most analytes, are lower in energy than the ionization potentials of common reversed-phase LC-MS solvents such as water, methanol, and acetonitrile. The low energy photons result in spectra with virtually no chemical noise and also ensure minimal fragmentation of the analyte allowing the protonated species of the radical cation to be identified.
- Ionizes widest range of compounds
- APCI, APPI, and combined APCI/APPI modes
- Krypton VUV light source reduces chemical noise
- Proven Thermo Scientific™ Ion Max™ ion source platform
