Quantitative gas-chromatographic determination of short-chain fatty acids in aqueous samples.

چکیده
We report the use of SP-1200 (Supelco Inc.) for quantitative gas-chromatographic determination of shortchain fatty acids (C2-C5) in stool water. The ratio of peak areas for these acids to that for 2-methylvaleric acid (internal standard) is linear for each acid from 60 to 1800 mg/liter. Lactic acid, occasionally present in stool in abnormally high amounts, is not detectable as the free acid on SP-1200, but is determined as its propyl ester on diethyleneglycolsuccinate.

متن کاملA gas chromatographic analysis of fecal short-chain fatty acids, using the direct injection method.
A simple, reproducible, and rapid gas chromatographic method for short-chain fatty acid determination in human feces was developed. It involves direct injection of fecal supernatants into the gas chromatograph, without any pretreatment. Contamination of the gas chromatographic column with nonvolatile fecal material was prevented by the use of a glass liner in the injector. This liner, which act...
متن کاملHigh sensitivity quantitative lipidomics analysis of fatty acids in biological samples by gas chromatography-mass spectrometry.
Historically considered to be simple membrane components serving as structural elements and energy storing entities, fatty acids are now increasingly recognized as potent signaling molecules involved in many metabolic processes. Quantitative determination of fatty acids and exploration of fatty acid profiles have become common place in lipid analysis. We present here a reliable and sensitive me...
متن کاملPhthalate interference in gas-chromatographic determination of long-chain fatty acids in plasma.
Phthalates leached from plastic tubing or other plastic devices may interfere with gas-chromatographic determination of long-chain fatty acids in plasma. In the case of hospitalized patients who have received infusions or had blood drawn through plastic tubing, gas chromatography/mass spectrometry may be required for accurate determination of such fatty acids.
متن کاملChromatographic methods in the determination of absolute and relative configurations of fatty acids.
Chromatographic techniques for determination of configurations of branched and substituted long-chain fatty acids, both absolute and relative, are reviewed. Gas-liquid chromatographic and thin-layer chromatographic procedures are emphasized.
