the aim of this research is to develop a silica gel and alumina column chromatography for separation of polycyclic aromatic hydrocarbons (pahs) and polychlorinated biphenyls (pcbs) into two groups. this is achieved by optimizing the cut-off volume of eluting solvent and weight ratio of silica gel and alumina. in this process mixture of pahs and pcbs divide in two groups and simultaneously other...

BACKGROUND In-hospital hypovitaminosis C is highly prevalent but almost completely unrecognized. Medical awareness of this potentially important disorder is hindered by the inability of most hospital laboratories to determine plasma vitamin C concentrations. The availability of a simple, reliable method for analyzing plasma vitamin C could increase opportunities for routine plasma vitamin C ana...

oDays High-performance liquid chromatography (HPLC) for analysis of phospholipids has traditionally employed ultraviolet detection of the eluted compounds. The evaporative laser light-scattering detector (ELSD) offers new opportunities for quantitative analysis of lipids. Phospholipids were isolated from crude and degummed oils prepared from soyheans subjected to storage at high moisture conten...
