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.
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.
From the experimental results, vacuum thermogravimetric analysis was concluded adequate for the quantitative determinating of lipids.
