In a closed container, the instrument system that achieves the sample pre-processing goals through the principle of microwave heating under high temperature and pressure conditions is called a microwave digestion system. Let's take a look at the principle and application of the microwave digestion instrument below.
The microwave digestion technology uses the penetrating ability and reactive capability of microwaves to heat reagents and samples in a sealed container, which can increase the pressure inside the sample preparation container, raise the reaction temperature, and greatly improve the reaction rate, thus shortening the sample preparation time. And the automated microwave digestion system can control the reaction conditions, improve the sample preparation accuracy, reduce environmental pollution and improve the working environment of laboratory personnel.
The traditional method for preparing samples using a porous digester or hot water bath requires several hours of digestion time. Even if a more advanced traditional digester is chosen and an exhaust gas absorption device is equipped to prevent the leakage of noxious gases during digestion, the results are still very difficult. Using the microwave digester system, only a few tens of minutes of digestion time are required. In digestion, because the digestion tank is completely sealed, there is no leakage of exhaust gas, and toxic catalysts and heating agents are not needed. The sealed digestion prevents sample loss due to the volatilization of exhaust gas.
Microwave oven: (safety protection door, automatic control system, exhaust system, magnetron, waveguide, microwave oven cavity, load plate, microwave digestion tank, temperature and pressure control tank, etc.), automatic monitoring system.
The microwave digester system, one of the automated laboratory systems, is widely used in sample preparation for atomic absorption spectroscopy (AAS), inductively coupled plasma atomic emission spectroscopy (ICP), inductively coupled plasma mass spectrometry (ICP-MS), gas chromatography (GC), gas chromatography-mass spectrometry (GC-MS), and other instruments.
Raykol Group is one of the most professional microwave digester manufacturers in China. Microwave digestion uses the penetrating ability and reactive capability of microwaves to heat reagents and samples in sealed containers, thereby increasing the pressure and reaction temperature of the sample preparation container. Under the conditions of microwaves and high-temperature sealing, the automated microwave digestion system is mainly used for sample preparation of AAS, AFS, ICP, and ICP-MS. Welcome to inquire.
