Wang QL, Fan LY, Zhang W, Cao CX.
PMID: 17723774
Anal Chim Acta. 2006 Nov 24;580(2):200-5. doi: 10.1016/j.aca.2006.07.073. Epub 2006 Aug 04.

An on-line stacking method based on moving reaction boundary (MRB) was developed for the sensitive determination of barbital and phenobarbital in human urine via capillary electrophoresis (CE). The optimized conditions for the method are: 60 mmol L(-1) pH 11.0...

Chiral separations using polymeric surfactants and polyelectrolyte multilayers in open-tubular capillary electrochromatography.

PMID: 14615987
Anal Chem. 2003 Nov 15;75(22):6097-104. doi: 10.1021/ac034452g.

In this study, fused-silica capillaries are modified using a polyelectrolyte multilayer (PEM) coating procedure in open-tubular capillary electrochromatography. The PEM coating was constructed in situ with alternating rinses of positively and negatively charged polymers. The quaternary ammonium salt poly...

A rapid, sensitive and specific liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was developed for the simultaneous determination of four barbiturates (phenobarbital, pentobarbital, amobarbital and secobarbital) in raw milk. The barbiturates were extracted using liquid-liquid extraction, ultrasonication and centrifugation, and...

J Pharm Biomed Anal. 1987;5(3):233-45. doi: 10.1016/0731-7085(87)80027-4.

The 60 MHz (1)H NMR spectra of racemic thiopental, 1, have been studied with the achiral shift reagent, tris(6,6,7,7,8,8,8-heptafluoro-2,2-dimethyl-3,5-octanedionato) europium(III), 2, and the chiral tris[3-(trifluoromethylhydroxymethylene)-d-camphorato] europium(III), 3, and tris[3-(heptafluoropropylhydroxymethylene)-d-camphorato] europium(III), 4. Enantiomeric shift differences, DeltaDeltadelta, were clearly observed for...

Sulpholane (tetramethylenesulphone) has been used as the medium for non-aqueous potentiometric titration of barbiturates and sulpha drugs with tetrabutylammonium hydroxide. Recoveries for 0.1-0.3 mmole of barbituric acid, phenobarbital, amobarbital, barbital, secobarbital, sulphapyridine, sulphadiazine and sulphamerazine were generally in the...
