Chloramphenicol determination in milk by liquid chromatography – tandem mass spectrometry
A high-performance liquid chromatography – tandem mass spectrometry (HPLC– MS–MS) method was developed for the determination of chloramphenicol (CAP) in milk products. Mass spectral acquisition was done using electrospray ionization in the negative ion mode applying multiple reaction monitoring of two diagnostic transition reactions for CAP (m/z 321→152 and m/z 321→257). Milk samples were extra...
متن کاملDisopyramide determination by gas chromatography, liquid chromatography, and gas chromatography--mass spectrometry.
Disopyramide is determined in serum by gas chromatography with a nitrogen-selective detector, by liquid chromatography, and by gas chromatography--mass spectrometry. Comparable results are obtained with the three techniques, with a within-run and between-run precision of 5 to 10% (coefficient of variation). Least-squares analysis of data on patients' sera, analyzed first by gas chromatography (...
متن کاملRapid determination of glutethimide (Doriden) by gas-liquid chromatography.
drugs and nonbarbiturate sedatives, the clinical laboratory has been literally bombarded with requests for special toxicologic analyses. One of the most popular of the nonbarbiturate sedatives is glutethimide (Doriden, Ciba) or -ethyl--phenylglutarimide. This agent has sedative-hypliotic properties and the usual dose is 250-500 mg. taken at bedtime. McBay and Algieri have reported death occurri...
متن کاملThe determination of methionine in proteins by gas-liquid chromatography.
Intact methionine residues in proteins were rapidly and precisely determined by measuring methyl thiocyanate released during the reaction with CNBr and separated by g.l.c. Conditions for the reaction and for chromatography on columns of Porapak P-S are described. The recovery of methyl thiocyanate from several methionine derivatives and analogues were examined. Carbamoylmethionine was adopted a...
متن کاملDetermination of morphine by electron capture gas-liquid chromatography.
We describe a micromethod for determining as little as 0.1 microgram of morphine per liter of human urine. The procedure is about 20-fold more sensitive than are currently used gas-liquid chromatographic methods. It is particularly suitable for use as a confirmatory method for large-scale radioimmunoassay screening tests. The procedure involves extraction of morphine from urine and analysis of ...
