Product Introduction
The ANKS-HH18 microwave vertical ashing device is developed based on the Enix microwave small sample ashing device. In the process of radioactive detection of biological samples, a large number of samples need to be collected for analysis due to the radiation generated by trace amounts of radioactive substances, that is, sample ashing is carried out to produce biological ash. The important difference between the ashing process of radioactive detection and ordinary ash preparation is that the former requires strict control of the temperature of the sample during the ashing process and cannot have high temperatures to prevent the sublimation and escape of nuclides. The Enix HH18 ashing device can complete the drying, carbonization, and ashing of biological samples in one go. A 12L ashing container with a processing capacity of 5kg takes about 32 hours to prepare animal samples; The preparation time for plant samples is about 6-8 hours, which saves time and increases sample testing time and cost compared to traditional muffle furnaces, electric heating plates, and oven conversion methods
Scope of application
Radiation Protection Research Institute, Occupational Disease Prevention and Control Institute, Entry Exit Inspection and Quarantine, Marine Monitoring, Nuclear Industry Research Institutions, Nuclear Power Plants, Nuclear Geology, Environmental Protection Department, Nuclear and Radiation Safety Supervision Station, Nuclear and Radiation Safety Center, Radiation Environment Monitoring Technology Center, Nuclear Facility Operation Unit Nuclear Industry Research Institute, Nuclear Science Related Research Institutes can quickly ashing a large number of biological samples such as grain crops, vegetables, grass, milk, aquatic products, meat, etc., and can also achieve sample digestion treatment

Using a cut-off circleWaveguideSealed structure, equipped with inductive suppressors and microwave leak prevention treatment, excellent national standard (≤ 5mW/cm2)
Microwave high-temperature system: mainly composed of a specially designed crucible, cavity, microwave, temperature measurement, insulation system, etc; The microwave ashing system completes the three processes of drying, carbonization, and ashing in the continuous ashing process of materials. Microwave drying can quickly complete dehydration under low temperature conditions, avoiding the effects of traditional drying time and high temperature on nuclide sublimation and drift. During the microwave pyrolysis carbonization stage, in a lean oxygen state, the microwave pyrolysis reaction releases exhaust gas until the sample is carbonized. During the ashing stage, the equipment introduces air, and the microwave high-temperature carbide begins to oxidize and decompose before the sample ashing is completed. The total time is ≤ 70 hours.
Automatic mode: Integrated implementation of drying, carbonization, and ashing, directly placing the collected fresh samples into a closed container
