Chromatography Summary: | Analysis of serum and urine samples was performed using a published LC-QTOF-MS acquisition method, which employed a 1290 Infinity II HPLC coupled to a 6550 QTOF-MS equipped with dual AJS electrospray ionisation source (Agilent, Cheadle, UK). Data acquisition parameters are detailed in brief below and in full in Supplementary Materials. Reversed-phase LC was performed on an Atlantis dC18 column (3×100 mm, 3 μm, Waters, Manchester, UK) maintained at 60 °C. Mobile phase composition was (A) water and (B) methanol, both with 5 mmol/L ammonium formate and 0.1 % formic acid. The elution gradient began at 5 % B 0–1 min and increased linearly to 100 % B by 12 min, held at 100 % B until 14 min, then at 5 % B for a further 5 min. MS data acquisition was performed in positive and negative ionisation polarity with mass range 50–1700 in 2 GHz mode with acquisition rate at 3 spectra/second. Sample injection volume was 1 and 2 µL in negative and positive polarities, respectively. |
