of Amsterdam, The Netherlands suspension in methanol; 10 yg standard

REMARKS - Sample prepared following ref. 172. The terminal side chain glucose units appear to give rise to peaks at m/z 96, 98, 110 and 126 (see Spectra A.1-A.4), whereas the most pronounced fragments from the glycerol moieties are thought to be m/z 61 (probably an EI fragment) and m/z 44. Peaks at m/z 36, 38 (HC1+") indicate the presence of chloride in the sample.
