摘要
Conditions were studied for the gas chromatography of normetanephrine, metanephrine, 3-methoxytyra-mine, 3-methoxy-4-hydroxyphenyl ethylene glycol, vanillylmandelic acid, and homovanillic acid with electron capture (EC) detection and mass spectrometry. Pentafluoropropionates (PFP) and heptafluorobutyrates were more stable and had higher EC-responses than the corresponding trifluoroacetates. These derivatives were also used to separate the amines on XE-60 and the deaminated metabolites on OV-17. The linear range with the63Ni EC-detector was 0,02-0.8 ng for the PFP-derivatives. Mass spectra were obtained from the perfluoroacylated, trimethylsilylated, and acetylated metabolites. © 1969, American Chemical Society. All rights reserved.
