Solid-Phase Extraction Columns for Lipid Analysis
Solid-phase extraction methods are being used for increasing numbers of applications in lipid analysis, but especially as a rapid means of isolating particular components for further analysis. Many different types of packing material are available enabling most different modes of chromatography to be used, including adsorption, reversed-phase, silver-ion and ion-exchange. However, there are occ...
متن کاملSolid phase extraction on sax columns as an alternative for ochratoxin A analysis in maize.
A sensitive and reliable method is described for the determination of ochratoxin A (OTA) in maize. An extraction and clean-up procedure was used, with chloroform-phosphoric acid as the extractant, and liquid-liquid partition and anion-exchange chromatography (SAX columns) for the clean-up. Quantification of toxin is achieved by high performance liquid chromatography (HPLC). Recoveries were betw...
متن کاملsalting-out procedure
DNA from archival Papanicolaou stained and unstained cytological smears was successfully isolated using a simple, rapid and inexpensive salting-out procedure. The quality of DNA was controlled by polymerase chain reaction (PCR) amplification of segments of the human P-globin, human P-actin and human papillomavirus LI genes. Only negligible differences in amplification efficiency were observed b...
متن کاملSilver ion chromatography using solid-phase extraction columns packed with a bonded-sulfonic acid phase.
Commercial solid-phase extraction columns packed with a stationary phase with bonded benzenesulfonic acid groups are readily converted to the silver ion form and can then be used for silver ion chromatography of lipids. To illustrate the utility of such procedures, methyl ester derivatives of fatty acids with zero to six double bonds were separated from each other by a simple stepwise elution s...
متن کاملLiquid Chromatography High-Resolution TOF Analysis: Investigation of MS for Broad-Spectrum Drug Screening
METHODS: We developed a broad-spectrum screening method on an ultra-performance liquid chromatography TOF mass spectrometer (UPLC-TOF-MS) using the MS mode. A diverse set of patient samples were subjected to a simple dilute, hydrolyze, and shoot protocol and analyzed in a blind manner. Data were processed with 3 sets of criteria with increasing stringency, and the results were compared with the...
