Microwave sample preparation system MS-6
Microwave sample preparation system MS-6 Designed for decomposition (mineralization) of samples of food products, food raw materials, soils, environmental materials, biological fluids, etc. when analyzing the chemical composition of samples using various methods: voltammetry, atomic absorption spectroscopy, spectrophotometry, etc. Also, the MS-6 microwave sample preparation system can be used in the microwave synthesis of various nanostructured compounds. The operating principle is based on the use of microwave energy for rapid volumetric heating of samples in sealed containers with oxidizing agents to destroy the organic and inorganic matrix that interferes with elemental analysis. Sample processing occurs at elevated pressures and temperatures. During the entire mineralization process, the pressure and temperature supplied to the magnetron are monitored in real time. The system is controlled using a button panel located on the front panel of the case. High performance The microwave system is equipped with a rotor that allows you to place up to 6 containers per load. Camera A specially designed chamber guarantees uniform energy distribution throughout the volume, eliminating the possibility of local overheating zones, which ensures flawless, reproducible sample preparation for analysis. 2mm thick stainless steel inner chamber with multi-layer fluoropolymer coating for long microwave system life. Rotor and Containers The liner is made of PTFE-TFM material, which can withstand high temperatures/pressures and prolonged exposure to acids. External casing made of reinforced PEEK material. The design of the containers allows for a quick process of assembling/disassembling the container. The containers are equipped with reusable safety diaphragms to safely relieve pressure in the event of an uncontrolled reaction. The twelve-position rotor is designed to accommodate 2, 4 or 6 containers. The use of sealed containers eliminates the loss of volatile components (mercury, arsenic, selenium, etc.) Security Safety is one of the advantages of the MS-6 system. A blast-resistant door with a double security system made of steel can withstand targeted impacts. External protective covers on containers. No disposable safety membranes. Cooling and ventilation The built-in air cooling system allows effective cooling to begin immediately after decomposition is complete, thereby significantly reducing the overall process time (cooling occurs in just a few minutes). The forced ventilation system allows the unit to be placed outside a fume hood. Sensors The MS-6 system is equipped with an immersion temperature sensor, which is located directly inside the reaction vessel and a pressure sensor located outside the microwave chamber, which provides protection against overheating of high-boiling reagents and simultaneous measurement of pressure and temperature in real time. Software Control is carried out using a built-in terminal with a color touch display and built-in software. Temperature and pressure data are displayed on the screen in graphical and digital form in real time and are stored in the non-volatile memory of the device. Graphic display of pressure and temperature values allows you to effectively select conditions when developing methods decomposition. An intuitive interface and ready-made pre-installed decomposition programs make it easier to work with the device and allow you to achieve excellent reproducibility of decomposition parameters. The user can create his own decomposition techniques. All parameters of the microwave sample preparation process are monitored in real time. Control and security systems Temperature and pressure in the reaction vessel are controlled using temperature and pressure sensors. Their feedback to the magnetron allows you to regulate the supplied power and ensures the most accurate reproduction of the specified sample decomposition conditions, as well as high operational safety. In addition to continuous monitoring and maintenance of the set temperature and pressure in the vessel, safety in an emergency is ensured by a number of additional systems, including an emergency magnetron shutdown device, a ventilation and exhaust system from the chamber reaction gases, as well as an explosion-proof installation chamber with a special door lock.
