Abstract
Abstract Gas-liquid chromatography, using a 5% SE-30 column and a hydrogen flame detector, has been used to quantitate vitamin E in pharmaceuticals. The gas chromatographic measurements were compared with the Emmerie-Engel results obtained on the same samples. Because of total recovery, smaller standard deviation, and simplicity, the GLC method was more desirable than the Emmerie-Engle method which includes a saponification preparatory step. The GLC method is also specific for each of the tocopherol analogs measured.
