MS:

MS ID:MS003428
Analysis ID:AN003677
Instrument Name:Thermo Q Exactive HF hybrid Orbitrap
Instrument Type:Orbitrap
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.
Ion Mode:POSITIVE
Capillary Temperature:275
Ion Spray Voltage:+3.5 kV
Automatic Gain Control:1E6
