Nitrogen carrier gas enhancement in GC-MS via ethylene dopant improves sensitivity and preserves EI-like spectra
Abstract Helium constraints motivate renewed use of nitrogen in GC–MS. We show that adding trace ethylene (about 9%) to nitrogen restores sensitivity by up to ~20-fold while preserving canonical 70 eV electron-ionization (EI) library matches for phthalates and polycyclic aromatic hydrocarbons. The g...
