New Materials Barrier Performance
Release time:
2021-09-06
The progress of the industry is not limited to technological breakthroughs, and the application and development of new materials is also of great significance. New material development refers to the research, discovery, development and promotion of various new materials on the basis of existing widely used materials. Generally speaking, only when new materials are superior in performance to existing materials can they have broader application prospects.
Barrier performance is more concerned about the development of new materials, especially in the application of new film materials and sheets. Common barrier properties are: water vapor permeability, oxygen permeability, air or other gas permeability.
Xitang Technology focuses on the deployment of barrier performance testing technology.

Evaporating Residue, Non-volatile Residue
2021-09-01
Pharmacy is a very rigorous process, and the quality of water has a major impact on the quality of pharmaceuticals. Ordinary water contains many trace elements and other substances, which cannot meet the needs of pharmaceutical production. Only purified water that meets the requirements can be used in pharmaceutical production. In this regard, the state has formulated a number of testing items to monitor the quality of purified water, and "non-volatile matter" is the most "torturing" item. The "most tortured" person in non-volatile matter testing? According to the Pharmacopoeia, 100ml of purified water is placed in an evaporating dish with constant weight to evaporate to dryness, and after drying to constant weight, the remaining residue shall not exceed 1mg; in addition, according to the general requirements of the Pharmacopoeia, the constant weight needs to be dried twice and weighed. The difference is less than 0.3mg. The 0.3mg constant weight requirement is very difficult for manual operation, so too many experimenters always struggle with this, and they think that the non-volatile item is too torturous. How to solve this "torture" problem? In today's increasingly high degree of automation, Xitang Technology has given the answer-a non-volatile constant weight meter. The constant weight instrument developed and designed by Xitang specifically to meet the requirements of constant weight, integrates the functions of water bath evaporation, heating and drying, drying and cooling, and constant temperature weighing. Instead of traditional water bath, oven, drying oven and balance, 2 weighing processes can achieve constant weight weighing. It not only perfectly meets the requirements of the standard 100%, but also greatly improves the efficiency of constant weight and the accuracy of the experiment. At this point, the "torturing" experiment is no longer tortured, the experimenter only needs to install the sample, and the rest is handed over to the automation. At present, more than ten listed pharmaceutical companies have applied the constant weight instrument for quality inspection. The constant weight instrument in the pharmaceutical industry can also be applied to: non-volatile matter in extracts of pharmaceutical packaging materials, loss on drying of raw materials, extracts of traditional Chinese medicines, and other constant weight requirements experiments.
