Preparative GC-MS spectra of alditol acetate (a and b) and perdeuteromethylated alditol acetate (c and d) derivatives. The patterns of prominent fragment ions are presented. An SP-2380 column was used for the analysis of alditol acetate derivatives. The temperature program was started at 60°C, with an increase of 40°C/min to 260°C and a hold at 260°C for 25 min. An Equity-1 column was used for the perdeuteromethylated alditol acetate derivatives. The temperature program was 80°C for 1 min, with an increase of 20°C/min to 180°C followed by an increase of 8°C/min to 280°C.
