Sample Preparation:

Sampleprep ID:SP001579
Sampleprep Summary:Fecal supernatants were serially diluted using 50% acetonitrile and 0.1% formic acid in water to obtain final dilution of 1:10,000. 500 µl of each sample were placed in glass vials (Wicom, Heppenheim, Germany) and stored at - 80 °C until LC-MS/MS analysis.For the analysis of sulfonates by LC-MS/MS-MRM, aliquots of 250 µl for each sample were centrifuged (14 000 x g, 4 °C, 5 min) and 50 µl of the supernatant stored at – 20 °C until further processing. Samples were thawed, centrifuged at 18 000 x g at RT for 2 min and the supernatant was diluted 1:10 000 in 50% aqueous acetonitrile. Subsequently, 500 µl of each sample were placed in glass vials (Wicom, Heppenheim, Germany) and stored at - 80 °C until LC-MS/MS analysis.
