不同厂家六号溶剂油对植物油中溶剂残留量测定结果影响的研究

THE INFLUENCE OF NO 6 SOLVENT FROM DIFFERENT FACTORIES ON THE RESULT OF DETERMINING RESIDUAL SOLVENT CONTENT IN VEGETABLE OIL

扦取 5份大豆油样品 ,分别使用两个厂家的六号溶剂油制备标准样品 ,利用峰高定量法和峰面积定量法测定溶剂残留量 ,测定结果不同。大多数情况下 ,植物油样品中六号溶剂油组成与标准样品中的不同 ,采用较高的记录仪纸速和峰面积定量 。

Five samples of soybean oil were prepared into standard samples with No.6 solvent oil of two factories respectively.The results of determination of residual solvent content were different by using of peak high for quantum and peak area for quantum.In most cases ,the composition of No.6 solvent in the sample of vegetable oil is different from the one in the standard sample,so using a higher paper speed in recorder and with peak area for quantum can get a more exact result for the residual solvent content.
