Countercurrent chromatography: a worthy technique for the direct measurement of liquid-liquid partition coefficients
Countercurrent chromatography (CCC) is a liquid chromatography technique in which the stationary phase is also a liquid. The solute separation is based on partitioning between the two immiscible liquid phases: the mobile phase and the support-free liquid stationary phase. Octanol-water partition coefficients (Po/w) of 17 βblockers and 17 sulphonamides were determined by CCC. Some of the Po/w co...
متن کاملVortex-Assisted Inverted Dispersive Liquid-Liquid Microextraction of Naproxen from Human Plasma and Its Determination by High-Performance Liquid Chromatography
Extraction and determination of naproxen from human plasma were performed using Vortex-Assisted Inverted Dispersive Liquid-Liquid MicroExtraction (VA−IDLLME) and High-Performance Liquid Chromatography (HPLC). The parameters affecting extraction recovery such as type and volume of extraction and disperser solvents, pH of sample solution, stirring rate, extraction time and salt addition were ...
متن کاملIsolation of porphyrins from biological materials by partition chromatography.
The present investigation was undertaken because of the need for a more practicable procedure for isolating pure porphyrins from biological materials. The existing methods, based primarily on solvent fractionation, on adsorption chromatography with calcium carbonate, talc, aluminum oxide, or other adsorbents, or on a combination of the two procedures, have failed in our hands to give an entirel...
متن کاملSEPARATION OF NONHISTONE HIGH MOBILITY GROUP (HMG) FROM HUMAN LYMPHOCYTES BY HIGH PERFORMANCE LIQUID CHROMATOGRAPHY
The high mobility group (HMG) of nonhistone proteins have been investigated using two high performance liquid chromatographic techniques (HPLC). Reversed-phase HPLC under conditions of 50 mM triethylamine adjusted to pH 2.2 with phosphoric acid (solvent A) and 95% acetonitrile in water (solvent B) was used to separate proteins primarily on the basis of differences in the overall hydrophobi...
متن کاملGas-liquid partition chromatography: the separation of volatile aliphatic amines and of the homologues of pyridine.
Fig. 6. Analysis of the volatile amines present in Chenopodium vulvaria L. Curve A: standard mixture ofmono-, diand tri-methylamines. Curve B: chromatogram of the amines present in an acid extract ofthe plant, showing the presence of only ammonia and trimethylamine. (Column length, 4ft.; liquid phase, hendecanol-iS% liquid paraffin (v/v); temp., 78 50; flow rate of nitrogen, 5.7 ml./min.; nitro...
