Chromatography:
Chromatography ID: | CH002727 |
Chromatography Summary: | Equilibration time was 4 min at 90% B, with 3.5 min at 0.35 mL/min, then 0.5 min at 0.25 mL/min. After sample injection, a gradient ran from 90% to 20% B over 17.5 min at 0.25 mL/min, then flow was increased to 0.35 mL/min for 1 min and held at 20% B at 0.35 mL/min for 3.5 min. |

MS Type: | ESI |
MS Comments: | Data were processed using Compound Discoverer 3.2 (Thermo). Minimum peak intensity was 5E5 for positive mode. Retention times were aligned across runs, quality control (QC) pooled sample areas were normalized per metabolite using a cubic spline method, requiring <50% relative standard deviation after correction for compound retention. Missing values were gap-filled based on real peak detection and metabolites with max sample area <5-fold that of the blank were censored. |
