Positive-ion electron impact and positive-ion chemical ionization mass spectra of 30 antihistamines H1 are presented. Drugs were extracted under alkaline conditions, and separated on a 25 m BP5 capillary
column. GC retention times are reported on both a retention indices basis as well as relative to SKF 525 A internal standard. While mass spectra were sometimes identical in electron impact mode, particularly for the ion m/z 58, using chemical ionization mode, characteristic ions were obtained.
