Separation of tocopherols by nano-liquid chromatography.
Nanoliquid chromatography (nano-LC) was used for the separation of tocopherols (delta-, gamma-, alpha-TOH), alpha-tocopherol acetate (alpha-TOH-Ac) and an antioxidant compound, namely butylated hydroxytoluene (BHT) used to prevent TOHs autoxidation. The separation was carried out in a fused silica capillary of 100 microm I.D. and 375 microm O.D. packed in our laboratory with RP18 silica station...
متن کاملPerchloroethylene Analysis by Chemical Oxidation and Determination of Intermediate Products by Gas Chromatography, Mass Spectrometry
Abstract Background and Objective: Perchloroethylene (PCE) is a chlorinated hydrocarbon used as a solvent in many industrial processes. In contaminated water and soil a great deal of PCE is found. This study aimed to determine the rate of decomposition of PCE occurred after advanced oxidation. Material and Methods: In this descriptive-analytic study conducted (2011) in public health faculty...
متن کاملSeparation of triglycerides by gas-liquid chromatography.
The parameters affecting the separation and quantification of triglycerides by gas-liquid chromatography have been investigated with the use of QF-1 and SE-30 as stationary phases and a flame ionization detector. The isothermal characteristics of a wide variety of triglycerides (carbon number 6 to 60) on both columns show that long retention volume is directly proportional to carbon number and ...
متن کاملSeparation of individual tocopherols from human plasma and red blood cells by thin-layer and gas-liquid chromatography.
A thin-layer chromatography-gas-liquid chromatography system has made it possible to separate the individual tocopherols for qualitative and quantitative determination in blood plasma and red blood cells. The peak of the individual tocopherols found in plasma and red blood cells were identified by their RF values and comparing their relative retention times with that of 5,7-dimethyltocol which ...
متن کاملIdentification and determination of different alkaloids from Atropa belladonna L. by Gas chromatography method
Background & Aim: A. belladonna (family: Solanaceae) is one of important pharmaceutical plants which contain tropane alkaloids. Tropane alkaloids are distinct group of secondary metabolites of the Solanaceae family. The most important alkaloids of A. belladonna are atropine and hyoscine that are used extensively because of their medicinal properties. There...
