working principle

The working principle of microwave digestion instrument is mainly based on the interaction between microwave and substances. Microwave is a high-frequency electromagnetic wave with a frequency between 300MHz and 300GHz, characterized by short wavelength and strong penetration. The specific principle is as follows:

Microwave heating mechanism: When microwaves pass through substances containing polar molecules (such as water, acid, etc.), these polar molecules will rapidly rotate and vibrate with the change of microwave electric field, thereby generating friction and collision, causing the kinetic energy and temperature of the molecules to increase. This heating method can achieve uniform heating of the sample, avoiding the hot spot and temperature gradient problems that exist in traditional heating methods.

High pressure accelerated reaction: During microwave digestion, the sealed digestion tank is under high pressure, which helps accelerate the digestion reaction of the sample and improve the digestion efficiency. At the same time, microwave heating can also cause overheating, where the digestion temperature may exceed the boiling point, further promoting the decomposition and reaction of the sample.

Stirring promotes mixing: The stirring phenomenon during microwave heating also helps to fully mix the solvent with the sample, further accelerating the progress of chemical reactions.
