Samples of 50 pi plasma, standard or control plasma, 20 pi internal standard and 10 pi dithiothreitol solution are thoroughly mixed (vortex) in 1-ml Eppendorf tubes. The tubes are left to stand at room temperature for 15 min. Samples are then depro-teinised by the addition of 500 pi deproteinising acetonitrile solution, with thorough vortex mixing followed by centrifugation at 14,000 rpm (11,000 x g) for 5 min (4°C). Tandem mass spectrometry analysis is performed on 200 pi of the supernatant reserved in appropriate vials. If the analysis is not performed immediately, samples can be stored at -20°C until analysis. [Pg.101]

Fig. 3.2.4 Structures of the isomers 2-methylbutyryl- and isovalerylcarnitine. These isomers can not be differentiated by acylcarnitine analysis as described here because both appear as butylated Cs-acylcarnitine esters at m/z 302. Differentiation would require an additional chromatography step prior to tandem mass spectrometry analysis... Fig. 3.2.4 Structures of the isomers 2-methylbutyryl- and isovalerylcarnitine.

Phylloquinone, menaquinone, and menaphthone have been extracted from serum into supercritical CO2 and separated with SFC, with detection at 250 nm (127). Serum, supported on celite, was transferred to extraction cartridges and extracted with supercritical CO2 at 45°C prior to the analysis of benzodiazepines, anabolic agents, and nonsteroidal anti-inflammatory drugs by HPLC (128). Phenobarbital, butalbital, pentobarbital, and thiopental have been extracted from human serum prior to liquid chromatography-negative-ion electrospray tandem mass spectrometry analysis (129). The sample was extracted with supercritical CO2 at 40°C and 507 bar with static extraction for 5 min followed by dynamic extraction for 30 min. Calibrations graphs were linear for 1-60 pg/mL of each barbiturate and the detection limits were 23, 25, 50, and 225 ng/mL of thiopental, pentobarbital, butalbital, and phenobarbital, respectively. In the determination of the cited analytes in serum spiked at the 10- and 50-pg/mL levels, the recoveries were 94.2-106.9% and the RSDs were 1.14-5.18% (three replicates). [Pg.562]

Johnson reported at the 59th TSRC, in 2005, on the results of the identification of spin-trapped vapor-phase free radicals in MSS via an ESI-triple quadrupole tandem mass spectrometry analysis method. Four alkoxyl free radicals were unequivocally identified (OC2H5, OC3H7, OC4H9, and OCjHjj). The superoxide free radical was also tentatively identified (27A56). [Pg.1248]
