1. Basic Information of the Instrument

Name: Microwave Digestion

Serial Number: 2019001149

Manufacturer:Thermo Fisher

Model Number: MILESTONE EthosUP

2. Usage

The ablation and extraction of samples.

3. Specifications and Technical Indicators

3.1 Hardware

3.1.1 the use of the most advanced dual magnetron microwave control technology (output power ≥ 1900W).

★3.1.2 The microwave emission mode can be divided into pulse and non-pulse, and it can be confirmed by microwave power curve. Magnetron has a lifetime warranty. While full power operation, microwave leakage is less than or equal to 0.05mW/cm2 (Providing international standard test methods and data), which can ensure the health of operators.

3.1.3 Multi-dimensional microwave energy output. The combination of “microwave scatterer technology” and “Power enable energy maximization technology” can ensure uniform energy distribution and optimization of microwave energy in the cavity.

★3.1.4 Large microwave digestion chamber (volume ≥ 70L) can ensure the processing of large quantities of samples. There are detailed dimensions of the working chamber and the whole machine.

3.1.5 The cavity body has a multi-layer PTFE coating, which can be antiseptic for more than or equal to 5 years.

3.1.6 Stainless steel self-priming door body [x2] [x3] can be self-priming closed, which can effectively prevent explosion and microwave leakage. It has a function of automatic translation lagging. When encountering an accident, it can automatically and quickly move outward. And it can automatically restore after the hidden danger.

3.1.7 Automatic locking system. The door body is equipped with a temperature control lock. The operators can set the temperature control door lock in the range of room temperature to 1000 ℃ through operating software to prevent the door body in the experimental process being accidentally opened to ensure the safety of the operators. When the door is opened, the microwave output power can be automatically cut off.

3.2 Temperature/Pressure Control System

3.2.1 The use of advanced PID control technology can automatically and continuously adjust the microwave power.

3.2.2 It is equipped with a high-precision infrared temperature control system. Only one infrared temperature sensor can control the temperature of all measured samples, avoiding the error between multiple sensors. Temperature control range: 0-350 ℃; sample temperature control accuracy: ± 1 ℃; temperature control response time ≤ 1 second. The temperature control accuracy can be displayed on the control terminal. And there is a digestion tank that can control and display the highest temperature, average temperature and the lowest temperature.

3.3 Control Terminal

★3.3.1 It is equipped with anticorrosive touch-type integrated/split dual-use intelligent control terminal and high-resolution color display screen, which makes it easy to be operated and help it control all operations of the microwave digestion system online from a distance. It is non-civilian mobile terminal.

3.3.2 Full-automatic digestion tank identification system. According to the number of samples digested by the user and the type of digestion tank, it can automatically adjust microwave output power size to ensure the reproducibility of each test.

3.3.3 Automatic over-temperature protection system. When the temperature in the digestion tank is higher than the set temperature, the microwave output will be cut off automatically to ensure the safety of operation. When the digestion temperature returns to normal, the system will automatically start to ensure that the sample digestion will not be interrupted.

3.3.4 Average power calculation function during microwave digestion can provide sufficient basis for the establishment of new methods.

3.3.5 The surface of the control terminal is treated with special anti-corrosion treatment.

3.3.6 Method and working data can be synchronized and saved to the controller and other computers and smart mobile terminals.

3.3.7 Multi-language operation interface, including Chinese operation interface.

3.4 High-pressure and high-throughput sample tank rotor.

3.4.1 High-temperature/high-pressure sample digestion tank. Each digestion tank has “elastic pressure relief valve” active pressure relief protection technology, which does not affect the sample to continue digestion after the pressure relief. The pressure relief process will not consume any part.

3.4.2 Maximum pressure of sample digestion tank: 120bar (1800psi).

3.4.3 Maximum temperature resistance of the sample digestion tank: 300°C [x5].

3.4.4 Sample digestion tank volume: 80ml, and the number of simultaneous treatments of the reaction tank: ≥ 15 bits.

3.4.5 Material of sample digestion tank and lid: PTFE-TFM.

3.4.6 Material protecting the outer tank: composite quartz fiber PEEKK which does not absorb any solvent and gas and will never deform.

3.4.7 After digestion, there are cooling methods of in-situ ordinary air cooling, forced air cooling and water cooling to cool down the rotors.

3.4.8 The digestion tank works in two ways which are continuous 360° rotation in the same direction and reciprocal rotation respectively to ensure uniform heating.
