Solutions MD Microwave Digestion System Introduction: Microwave digestion is the preferred sample preparation method for the determination of trace or ultra-trace metal elements. After nearly 40 years of development, microwave digestion technology has been widely used. The sample and the corresponding reagent are placed in a high temperature and high pressure sealed sample can or open container, and under the action of microwave, according to a certain experimental method, the sample and the reagent undergo rapid and intense physical and chemical reactions, which not only shortens the sample processing time. And achieve the least amount of acid, the lowest background value and complete recovery and other traditional sample processing methods can not match the advantages. The instrument can be used in sample preparation for digestion, extraction, protein hydrolysis and other analytical chemistry, such as atomic absorption spectrometry (AAS), atomic fluorescence spectrometry (AFS), inductively coupled plasma optical emission spectrometry (ICP-AES). Sample preparation of analytical instruments such as inductively coupled plasma mass spectrometry (ICP-MS), high performance liquid chromatography (HPLC), and gas chromatography (GC). Features: 1. Microwave accelerates chemical reaction, and the digestion speed is fast, which is 10-100 times faster than the general hot plate method; 2. Microwave heating uses high-pressure sealed cans, the sample is thoroughly digested, and the loss of volatile elements is greatly reduced; 3. Microwave digestion uses less reagents, reducing the blank value and background of the sample; 4. The entire digestion process is carried out under closed conditions, and the acid reagent will not pollute the environment, which is conducive to protecting the environment and the health of the experimental personnel; 5. The energy saving effect is remarkable, and the energy saving is about 80% than the traditional method; 6. Parallel and repeatability of the same batch of treated samples.
