Comparison study of the extraction methods of paraquat in post-mortem human blood samples.
The most important step for Paraquat analysis in post-mortem human blood (PMB) is its extraction from the specimens, as Paraquat is insoluble in organic solvents due to its ionic form. The most common extraction method, solid phase extraction (SPE), has been used for the extraction of Paraquat from PMB. However, SPE procedures are somewhat time-consuming, and resulted in unsatisfactory recovery...
متن کاملExtraction of Lipids from Human Blood Plasma Using Compressed Gases
Lipids were extracted from human blood plasma using suband supercritical fluids. An extraction plant was specifically designed to allow the treatment of plasma with compressed propane, dimethyl ether (DME) and nitrous oxide (N2O) as solvents. Experiments were performed using suband supercritical gases as mild solvents to remove the lipid fraction without denaturing valuable proteins or affectin...
متن کاملSolid Phase Extraction Using Modified Magnetic Iron Oxide Nanoparticles for Extraction and Spectrofluorimetric Determination of Carvedilol in Human Plasma Samples
A new analytical approach was developed involving magnetic solid–phase extraction and spectrofluorimetric determination of carvedilol in human plasma samples. A plasma sample was prepared and adjusted to pH 8.2–10, then carvedilol was quickly extracted using iron oxide magnetic nanoparticles modified by the surfactant cetyltrimethylammonium bromide and determined to apply spectrofluorimetry...
متن کاملRapid purification of a high-affinity plasminogen activator from human blood plasma by specific adsorption on fibrin/Celite.
A preparation of fibrin precipitated over a solid Celite (diatomaceous earth) matrix that selectively binds 50-70% of the plasminogen activator present in human blood plasma is described. Affinity chromatography of plasma on fibrin/Celite followed by gel filtration led to a 29,000-fold purification of the plasminogen activator. The activator, referred to as the high-affinity plasminogen activat...
متن کاملDetermination of paraquat in human blood plasma using reversed-phase ion-pair high-performance liquid chromatography with direct sample injection.
This report describes the determination of paraquat (PQ) in human blood plasma samples by a direct-injection reversed-phase ion-pair chromatographic method. Blood plasma filtrate was injected directly into the LiChrospher(R) RP-18 alkyl-diol silica (ADS) precolumn integrated in a column switching system using a mixture of 3% 2-propanol and 10 mM sodium octane sulfonate (SOS) in a 0.05 M phospha...
