Webbeen shown in using the HILIC separation with mass spectrometry detection. A fourfold increase in sensitivity with HILIC mode was produced due to more efficient spraying and desolvation in the ESI-MS source as compared to RPLC. This generated less baseline noise and a more intense MS signal. Figure 3 shows the elution order and selectivity of the WebDec 1, 2016 · Ultrahigh performance liquid chromatography-tandem mass spectrometry (UHPLC–MS/MS) has been used to determine TMAO [20], [21], [22], or simultaneously TMAO and TMA in plasma or urine [23]. The current study aimed at developing and validating a UHPLC–MS/MS method for the simultaneous quantification of TMA, TMAO, and taurine.
