Optimisation of Urine Sample Preparation for Headspace-Solid

Nov 25, 2020 · We propose that adding 0.2 mL of 2.5 M H 2 SO 4 to 1 mL of urine within a 10 mL headspace vial is the optimal sample preparation prior to HS-SPME-GC-MS analysis. We hope the use of our optimised method for urinary HS-SPME-GC-MS analysis will enhance our understanding of human disease and bolster metabolic biomarker identification.
