摘要

•DIMETRIS – a new silylating reagent for the derivatisation of NSAIDs.•Derivatising properties of DIMETRIS compared with those of BSTFA and TMSD.•Possibility of using MS and ECD detectors for the GC determination of new derivatives.•Study of the influence of complex matrices on derivatisation and GC–MS analysis.•A new SPE-GC–MS method for determining NSAIDs based on derivatisation with DIMETRIS.
