文献和实验Quantitation of Oxycodone in Blood and Urine Using Gas Chromatography-Mass Spectrometry (GC-MS)
are fortified with deuterated internal standard and a five-point calibration curve is constructed. Specimens are extracted using mixed-mode solid phase extraction and derivatized with N,O-bis(trimethylsilyl)trifluoroacetamide (BSTFA) producing trimethylsilyl
and VMA from the acidified samples, and the extract is dried. The residue is treated with bis-(trimethylsilyl)trifluoroacetamide (BSTFA), 1% trimethylchlorosilane (TMCS), and pyridine to prepare trimethylsilyl derivatives of HVA and VMA. The derivatized
can be carried out using gas chromatography-mass spectrometry, organic acids must be converted into more thermally stable, volatile, and chemically inert forms, mainly trimethylsilyl ethers, esters, or methyl esters.
