无水葡萄糖试验操作程序所需的仪器有;分析天平、转子流量计、红外分光光度计、恒温干燥箱、恒温水定量箱、三角瓶、比色管、试管、酒精灯、吸管、吸量管、容量瓶、蒸发皿、坩埚酸性滴定管、马弗炉、衡器等。现在让我们来看看无水葡萄糖测试的程序。
The instruments needed for the operation procedure of anhydrous glucose test are: analytical balance, rotameter, infrared spectrophotometer, constant temperature drying oven, constant temperature water quantitative oven, triangle flask, colorimetric tube, test tube, alcohol lamp, straw, pipette, volumetric flask, evaporating dish, crucible acid dropping tube, muffle furnace, weighing instrument, etc. Now let's look at the procedure for testing anhydrous glucose.
1. 每次测量前，应使用溶剂进行空白校正。测量后，应再次校准溶剂，以确定测量的零点
1. Before each measurement, use solvent for blank correction. After the measurement, the solvent shall be recalibrated to determine the zero point of the measurement
没有变化，如果在第二次校正时发现零的变化，应该重新测量旋转。
There is no change. If zero change is found in the second correction, the rotation should be re measured.
2. 配制和测量溶液时，应将温度调节到0.5^C(或每个品种规定的温度)。
2. When preparing and measuring the solution, adjust the temperature to 0.5 ^ C (or the specified temperature of each variety).
3.待测液体或固体的溶液应完全溶解，待测液体应澄清。
3. The solution of the liquid or solid to be tested shall be completely dissolved, and the liquid to be tested shall be clarified.
更后，物质的旋度与光源的测定、波长的测定、溶剂的测定、浓度的测定、温度的测定等因素有关。因此，当表示物质的特定旋度时，应指出测定条件。因此，我们在检测无水葡萄糖时，一定要注意相关的事项和要求，同时也要注意具体的操作方法，以便更好的使用。
Finally, the rotation of matter is related to the measurement of light source, wavelength, solvent, concentration and temperature. Therefore, when the specific curl of a substance is expressed, the determination conditions should be indicated. Therefore, when we detect anhydrous glucose, we must pay attention to the relevant matters and requirements, and also pay attention to the specific operation methods in order to better use.
