This month we feature an article by Marcos Bouza and colleagues reporting on the analysis of volatile organic compounds (VOCs) by pulsed glow discharge (PGD) coupled with time‐of‐flight mass spectrometry. This instrument configuration is presented and discussed as an alternative to the more traditional GC‐MS options that typically incorporate either an electron ionization and/or a chemical ionization...
Pulsed glow discharge (PGD) coupled to time of flight mass spectrometry (TOFMS) has been investigated for volatile organic compound (VOC) identification and determination. Optimization of PGD operational conditions (chamber design, applied power, pressure and duty cycle) was performed using acetone and benzene as model compounds. During the different optimizations, molecular, fragment and elemental...
