The method of testing vitamin E acetate
To test vitamin E acetate, prepare the first heavy equipment. A precise measuring device is required, such as a pipette, a balance, etc., must be accurate and accurate to measure accurately.

The method of testing is often the technique of chemical analysis. One is high-performance liquid chromatography. First prepare the liquid of the sample, dissolve the substance to be tested into a soluble agent in an appropriate proportion, shake and mix well to make it fully soluble. Then inject it into a liquid chromatograph to adjust parameters such as flow rate, column temperature, detection wavelength, etc. Observe the peak of its chromatography, compared with the peak of the standard product, according to the retention time of the peak, the peak area, etc., to determine the presence and content of vitamin E acetate.

Furthermore, gas chromatography can be used. The sample needs to be treated first, or the step of derivatization makes it suitable for gas phase analysis. Then the sample is injected into a gas chromatograph. According to the situation of its peak, it is compared with the known standard gas phase diagram to determine the characteristics and amount of vitamin E acetate.

In addition, the method of chemical titration can also be used. Choose a suitable titrant and add it dropwise to the sample solution according to the quantitative relationship of its chemical reaction. The content of vitamin E acetate can be obtained by calculation based on the indicator discoloration or potential jump as the end point. However, this method requires the operator to be skilled in manipulation and precise control of the reaction conditions.

Detection of vitamin E acetate, each method has its own advantages and disadvantages. High performance liquid phase and gas chromatography, with high accuracy, can measure trace components; although the chemical titration method is more traditional, it is convenient to operate and useful in specific scenarios. The operator should choose the appropriate method according to the characteristics of the sample, the purpose of analysis and the existing conditions, so as to achieve the purpose of accurate detection of vitamin E acetate.
