Fast Microwave Digestion Instrument, 40-Bit High-Throughput Microwave Digestion System. (CAT#: STEM-SPE-0027-TP)

Using the microwave digestion sample treatment technology, combined with the AAS method to determine the available metal elements such as Ag, As, Cr, Cu, Mo, Pb, Sn, Co in the soil, the research shows that the microwave digestion method is compared with the traditional acid hydrolysis method. Not only the analysis results are consistent, but also has the advantages of rapidity, high efficiency, cleanliness and less pollution, which can fully meet the requirements of environmental analysis.
The pretreatment methods of food samples are divided into two categories: open digestion and closed digestion. The former includes dry ashing method and electric hot plate digestion, and the latter includes pressure tank digestion and microwave digestion. In contrast, closed digestion can avoid the influence of the environment, and the loss of the test substance is small, the consumption of reagents is small, and the digestion speed is fast. A method for the determination of arsenic and mercury in cosmetics by atomic fluorescence spectrometry was established. The method used microwave digestion of pretreated samples and atomic fluorescence spectrometry to simultaneously determine the content of arsenic and mercury in cosmetics. Conclusion The microwave digestion-dual-channel atomic fluorescence spectrometry method for the simultaneous determination of arsenic and mercury in cosmetics has the advantages of simple operation, rapidity, low detection limit, high sensitivity and accurate results, and is suitable for the simultaneous determination of arsenic and mercury in cosmetics.
