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 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 mono- and diglycerides by gas--liquid chromatography.
The parameters affecting the separation and quantification of trimethylsilyl ethers of mono- and diglycerides have been investigated by gas-liquid chromatography with QF-1 and SE-30 as stationary phases and a flame ionization detector. Results have been compared with those obtained earlier for triglycerides. The isothermal characteristics of a range of trimethylsilyl ethers of mono- and diglyce...
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 کاملSeparation of aminoglycosidic antibiotics by gas-liquid chromatography.
Eighteen aminoglycosidic antibiotics and their degradation products, containing 2-deoxystreptamine as a commonmoiety, were separated by gas-liquid chromatography. The largest compounds examined included the pentacyclic lividomycins A and B. These compoundswere separable from each other either as pertrimethylsilyl derivatives or N-trifluoroacetyl pertrimethylsilyl derivatives on a single column ...
