Microwave digestion technology is to use the penetration of microwave and activate the reaction ability to heat the reagent and sample in the closed container, which can increase the pressure in the sample preparation container and increase the reaction temperature, thereby greatly improving the reaction rate and shortening the time of sample preparation.
Microwave digestion technology uses the penetration and activation of microwave reaction ability to heat the reagent and sample in the closed container, which can increase the pressure in the sample preparation container and increase the reaction temperature, thereby greatly improving the reaction rate and shortening the sample preparation time. And the reaction conditions can be controlled, so that the sample preparation accuracy is higher. Reduce pollution to the environment and improve the working environment of experimenters. Traditionally, samples have been prepared in a porous digester or in a cooking oven, and the digestion time of the sample is usually more than several hours. Even if a more advanced traditional digester is used, equipped with an exhaust gas absorption device, it is difficult to avoid the leakage of exhaust gas during digestion and produce a very choking odor. The microwave digestion system is used to prepare the sample, the digestion time only takes tens of minutes, and the digestion tank is completely closed, so there will be no exhaust gas leakage, and there is no need for toxic catalysts and heating agents. Closed digestion avoids sample loss due to volatilization of exhaust gases.
Microwave Digestion Instrument Use: Microwave digestion instrument is an advanced sample processing equipment, which is mainly used for digestion, dissolution and preparation of various samples in the laboratory. Here are the main uses of a microwave digester:
1.Sample digestion: The microwave digestion instrument can quickly and efficiently digest a variety of samples, such as biological samples, soil, food, ores, etc. By mixing the sample with acids, alkalis or other chemical reagents, the organic and inorganic substances in the sample are rapidly broken down under the action of microwaves, and finally a clear and transparent solution is obtained.
2.Dissolve samples: In addition to being used for digestion, microwave digesters can also be used to dissolve samples. In some experiments, the sample needs to be completely dissolved in a specific solvent for subsequent analytical testing. The microwave digestion instrument can speed up the dissolution of the sample, improve the dissolution efficiency, and provide more accurate and reliable data for subsequent testing.
3.Sample preparation: In many experiments, pretreatment of samples such as separation, purification, and concentration is required. The microwave digestion instrument can efficiently prepare samples through various chemical reactions and physical separation techniques, and provide high-quality samples for subsequent analysis and testing.
4.Reaction synthesis: In addition to sample processing, microwave digesters can also be used for chemical reaction synthesis. Through microwave heating and special reaction conditions, various chemical reactions and synthesis processes can be completed in a short time. This synthesis method has the advantages of high efficiency, rapidity, and environmental protection, and provides a new way for chemical research and industrial production.
In short, as an efficient, fast and environmentally friendly sample processing equipment, microwave digestion instrument is widely used in various fields, providing reliable support and help for scientific research and industrial production.
