On Vitamin E acetate test

the nature of vitamin E acetate must be measured by a rigorous method. Today, the main points of its measurement are described in detail.

The first is sampling. When selecting the right place, timely and appropriate source samples, make sure to be representative. And the sampling device must be clean and clean to prevent impurities from disturbing it.

The second is the backup device and the reagent. The device needs to be accurate, such as the measuring device must be correct, so that the amount is correct; the reagent must be pure and good, according to the recipe, to ensure its quality and stability.

As for the detection method, HPLC is often the best. Adjust the parameters of the instrument to make the column temperature, flow rate, and detection wavelength all suitable. At the time of injection, the amount must be uniform and accurate, and the shape, height and area of the peak should be observed, and the content should be determined by comparing it with the standard sample.

Or use chemical methods. Based on its chemical properties, through reaction, titration and other steps, the amount should be calculated according to the change of the quantity. However, chemical methods are easily disturbed by other things, so be careful.

When testing, all conditions must be constant. Temperature, humidity, vibration, etc. cannot be ignored, and the results will be different if they are slightly changed. Remember each step in detail. If there is a difference pool, the cause can be found.

After the end, the test is completed, and the results are analyzed. Those who conform to the regulations, praise its quality; those who disagree, investigate its source, and change its method to achieve good.

Measuring vitamin E acetate is related to people's livelihood, and must be respectful and careful, and must not be slack in the slightest.
