In many analytical fields, in order to obtain trace amounts of target components, it is necessary to preprocess the test samples, which mainly includes basic steps such as sample extraction (extraction), concentration, purification, and re concentration. Among them, how to quickly and non destructively concentrate is a crucial step.JRY-MNMicrowave concentration utilizes negative pressure, microwave heating, nitrogen blowing, and other methods to rapidly concentrate samples,solvedTraditional concentration methods are cumbersome and time-consuming in converting samples、During the processing, there is a significant amount ofToxicvolatile gas、Low degree of automation、Disadvantages such as inaccurate quantification.
