5 / 0.5 / 20 / SPE-Silylation
SPE: solid-phase extraction
Silylation Method
Before silylation, the extracted solutions were dried under a gentle nitrogen stream, and then the dry materials were treated with 0.4mL of anhydrous prridine, 0.2mL of hexamethyldisilazane and 0.1mL of chlorotrimethylsilane. The mixture was shaken for 1min and then stand for 5min at room temperature. At last, the samples were centrifugated at 12000 r/min to get the supernatant fluid prior to GC-MS analysis.
