無水葡萄糖試驗操作程序所需的儀器有;分析天平、轉(zhuǎn)子流量計、紅外分光光度計、恒溫干燥箱、恒溫水定量箱、三角瓶、比色管、試管、酒精燈、吸管、吸量管、容量瓶、蒸發(fā)皿、坩堝酸性滴定管、馬弗爐、衡器等。現(xiàn)在讓我們來看看無水葡萄糖測試的程序。
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. 每次測量前，應使用溶劑進行空白校正。測量后，應再次校準溶劑，以確定測量的零點
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
沒有變化，如果在第二次校正時發(fā)現(xiàn)零的變化，應該重新測量旋轉(zhuǎn)。
There is no change. If zero change is found in the second correction, the rotation should be re measured.
2. 配制和測量溶液時，應將溫度調(diào)節(jié)到0.5^C(或每個品種規(guī)定的溫度)。
2. When preparing and measuring the solution, adjust the temperature to 0.5 ^ C (or the specified temperature of each variety).
3.待測液體或固體的溶液應完全溶解，待測液體應澄清。
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，物質(zhì)的旋度與光源的測定、波長的測定、溶劑的測定、濃度的測定、溫度的測定等因素有關。因此，當表示物質(zhì)的特定旋度時，應指出測定條件。因此，我們在檢測無水葡萄糖時，一定要注意相關的事項和要求，同時也要注意具體的操作方法，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.
