- Different chemical classes of VOCs were analysed by three ionisation methods: the oldest gold standard, the electron ionisation(EI), was compared to chemical ionisation (CI) and to atmospheric pressure photoionisation (APPI), a more recent and rarestone. Methodological development on the APPI source coupled to an Orbitrap Fusion, was able to set the best parameters forVOCs high-resolution analysis. LODs calculation has shown a good sensitivity for EI and CI when methane was used as areagent gas, but APPI, despite in-source fragmentation, is a promising technique for co-elution resolution problems.
