Detection of Gas-Phase Formaldehyde via C2H5O+ Produced by VUV Illumination and Enhanced by Doping Propionaldehyde
{{output}}
Formaldehyde (CH2O) is one of the main indoor organic pollutants due to its carcinogenicity and teratogenicity. However, CH2O has been an undetectable species for common VUV lamp-based photoionization mass spectrometry (PI-MS) due to its high ionization energy... ...
