Molar mass distributions of silicone oil samples were determined by supercritical fluid chromatography (SFC), MALDI-TOF MS and their off-line combination. SFC was used to separate silicone oils on a micropacked capillary column. The fractions for the identification studies were obtained from an SFC run at defined time intervals. MALDI-TOF MS was used for the identification of individual oligomers in the separated fractions. The determined molar mass distributions based on SFC and MALDI-TOF MS measurements were compared and are in good agreement.
