Application of solid phase microextraction to the determination of strychnine in blood

Determination of quinalphos in blood and urine by direct solid-phase microextraction combined with gas chromatography–mass spectrometry

“…The obtained recovery values were higher than those normally seen in SPME methods [20], namely in the determination 6. Chromatogram corresponding to a real blood sample (case 21: 1.12 g/mL).…”

Determination of low molecular weight volatiles in Ficus carica using HS-SPME and GC/FID

“…Methods using SPME technique save preparation time, solvent purchase and disposal costs and can improve the detection limits (Dong et al, 2006). Actually, the SPME technique has been successfully applied to the analysis of volatile and semi-volatile organic compounds from environmental, biological and food samples (Barroso et al, 2005;Guedes de Pinho et al, 2008, namely fruits (Ibañez, Lopez-Sebastian, Ramos, Tabera, & Reglero, 1998).…”

Simultaneous determination of five toxic alkaloids in body fluids by high-performance liquid chromatography coupled with electrospray ionization tandem mass spectrometry

“…Several methods have been proposed for determination of Brucine, Strychnine, Ephedrine, Aconitine and Colchicine in body fluids as well as in herbal medicines, including the use of HPLC [12,13], liquid chromatography-mass spectrometry (LC-MS) [14,15], gas chromatography (GC) [16], GC-MS [17,18], capillary electrophoresis (CE) [19], etc. However, some shortcomings exist in these methods, such as long analytical time, complex procedures.…”
