Determination of the melting point is to identify the nature of the basic means of material, but also one of the important methods of purity determination. Therefore, the melting point analyzer in the chemical industry, pharmaceutical research, according to an important position, is the production of drugs, spices, dyes and other essential organic crystal material instruments. The attention of the problem can improve the life of the instrument.
1. The sample must be dried as required, crushed in a dry and clean mill, hit the capillary with a free fall to fill the sample, and the height of the fill should be the same, the specific requirements should be consistent with Pharmacopoeia.
2. Care must be taken when inserting and removing the capillary tube to avoid breaking.
3. Linear heating rate is different, the greenhouse results are inconsistent, requiring a specified specification.
4. The best sample filled with five capillaries, respectively, after the determination of the average of three readings taken as the measurement results in order to eliminate the capillarity and sample preparation filled by accidental errors.
5. The capillary tube inserted into the instrument before the application of a soft cloth to remove contaminated material, so oil bath soiled.
6. If you need to replace the oil bath tube, proceed as described in Preparations for Use.
