説明

A new technique using thermobalance for the quantitative analysis of lipids was conducted on the following mixed samples : [1] stearic acid (SA) and tristearoylglycerol (TSG); [2] TSG and trilinoleoylglycerol (TLEG); [3] SA, dimer acid (DA), and TSG, ; [4] 1-monostearoylglycerol (1-MSG), 1, 3-distearoylglycerol (1, 3-DSG), and TSG ; [5] SA, 1-MSG, 1, 3-DSG and TSG.<BR>For mixed samples of [1], [2], [4], and [5], good separatability was attained under each condition. However, for mixed samples of [3] SA could be separated, but DA and TSG were not successfully separated because of molecular weight distribution of DA and interactions between DA and TSG.<BR>From the experimental results, vacuum thermogravimetric analysis was concluded adequate for the quantitative determinating of lipids.
