Fully methylated methyl x-deoxy-x-fluoro-PD-galactopyranosides were studied using electron impact (EI) and chemical ionization (CI) mass spectrometry and by gas chromatography (GC)/mass spectrometry. Metastable daughter-and parent-ion measurements and high-resolution measurements were used to evalua
