In the field of radioactive nuclide pretreatment, routine radioactive detection of biological samples usually requires a large amount of sample concentration and enrichment. Ashing method is a necessary volume reduction method. At the same time, because the types of biological environment samples to be tested vary greatly, involving animals, plants, food, air, soil, and liquids, there are characteristics of short testing time, multiple types, and heavy tasks; Based on years of experience in microwave sample preparation, our company has developed a high-capacity, high-throughput, and high-efficiency microwave drying carbonization ashing device, providing a new high-capacity rapid ashing technology for the pre-treatment of radioactive analysis samples.
