You will get the best results analyzing spectra acquired with NMR parameters similar to those used to build the metabolite library. The Chenomx metabolite library was acquired between pH 4 and 9 at a temperature of 298 K (25 °C), with an acquisition time of 4 s and recycling delay of 1 s. The recycle delay includes a 990 ms saturation pulse on water. Our 1D pulse sequence is NOE-based, with a short mixing time of 100 ms. The mixing time also includes a water saturation pulse. The length of the proton 90° pulse (pw) was calibrated to maximize the intensity of the DSS peak.
