摘要：

Both supercritical fluid chromatography (SFC) and time-of-flight secondary ion mass spectrometry (TOF-SIMS) provide well-resolved signal intensities of low molecular weight poly(dimethylsiloxane) (PDMS) oligomers. To determine the achievable accuracy of these independent analytical methods, a direct comparison was performed on PDMS oligomers in the mass range from 1000 to 10 000 Da. Results obtained by SFC and TOF-SIMS fit well up to mass 3000 Da whereas remarkable differences occur for higher masses due to mass discrimination effects. These have been found to be more pronounced for SFC than for TOF-SIMS.
