The smart microwave digestion system comes in various materials and capacities to choose from. It can be equipped with a full-fluorine digestion tank or a double-layer digestion tank, which can resist accidental explosions and microwave leaks, and improve microwave leakage caused by the loose structure of traditional doors. With a diamond body and thickened and reinforced special stainless steel microwave resonant cavity, the risk can accommodate various digestion tanks and process multiple samples. The furnace door is composed of multiple protective layers, and the furnace chamber is coated with multiple layers of PTFE, greatly improving the service life and safety of the instrument. The optimized anti-flow groove structure design can eliminate the hidden danger of microwave leakage caused by instrument gap. The automatic shutdown function when the door is opened can automatically cut off the microwave after the door is opened actively or passively to protect the user's safety. The efficient exhaust system design can realize fast and safe air-cooling and improve operation efficiency.
1. Use temperature and pressure control systems. Operators can observe the data and curves of temperature and pressure changes to understand the operation of the microwave digestion system machine. When the slope is out of control, its software module can actively stop running, which greatly reduces the possibility of tank explosion.
2. Equipped with a real-time abnormal monitoring system for temperature and pressure. When the temperature and pressure control system fails, the system will detect and stop the operation in a timely manner as a backup measure to ensure safety.
3. Use high-temperature container materials.
As an effective sample preparation method, microwave digestion can meet the requirements of modern instrument analysis for sample preparation. The microwave digestion system has the advantages of fast heating speed, uniform heating, less reagent consumption, low blank value, and high energy efficiency. Especially in the analysis and detection of volatile elements, it can maintain the integrity of samples well, and the sample recovery rate can be high.
The acids widely used for digestion samples are nitric acid, hydrochloric acid, hydrofluoric acid, hydrogen peroxide, etc. These are good microwave absorbers. Different mixed acids are often used according to different samples. Nitric acid and hydrogen peroxide are often used. In special cases, nitric acid and perchloric acid are also used. However, perchloric acid and organic matter may explode, so most of them have been pretreated under normal pressure. They are used less in closed digestion.
The smart microwave digestion system can quickly process multiple complex samples in the same batch to ensure the recovery rate of volatile elements. It is used for acid digestion and solvent extraction of various samples, such as soil, food and agricultural products. Its ability to process complex samples (such as environmental edible oils) can exceed 0.5 grams.
