Allgemeine Beschreibung
Anwendung
- Development and validation of a high-performance liquid chromatographic (HPLC) method combined with UV detection to determine four short-chain fatty acids— formic acid, acetic acid, propionic acid, and butyric acid, and lactic acid in bacterial culture samples after their liquid-liquid extraction (LLE)
- Simultaneous analysis of 10 volatile and non-volatile organic acids in 18 samples of Korean traditional fermented soybean paste, doenjang, by HPLC combined with refractive index detector and gas chromatography coupled with flame ionization detector (GC-FID)
- Determination of butyric, lactic, acetic, and propionic acids in sour cassava starch waste-water samples by reversed-phase high-performance liquid chromatography (HPLC) and capillary electrophoresis (CE), both coupled with diode array detection (DAD)
- Multi-residue analysis of six short-chain fatty acids— acetic acid, propionic acid, butyric acid, isobutyric acid, valeric acid, and isovaleric acid, in biological samples of mice colon content by a gas chromatographic method combined with flame ionization detector (GC-FID)
- Packed-fiber solid phase extraction (PFSPE) of eight short-chain fatty acids using polypyrrole nanofibers, from urine samples of children for quantification by gas chromatography-mass spectrometry (GC-MS)
- Multi-residue analysis of 76 volatile compounds from jujube extract samples by gas chromatography-mass spectrometry (GC-MS) after their extraction by steam distillation combined with drop-by-drop extraction

Protokolle
In this study, SPME was used for the analysis of free fatty acids in Parmesan cheese using a 65 μm Carbowax/divinylbenzene (DVB) SPME fiber. Headspace extraction of the cheese sample was conducted at 65 °C for 15 minutes and analyzed by GC with FID detection. SPME is ideal for analyzing the volatiles associated with solid food samples. The phase chemistry of the Nukol GC column provides excellent peak shape of acidic compounds.
