Microwave Digestion System

1. Microwave Technology: A vertical waveguide design and three-dimensional output technique are employed to achieve a highly uniform microwave field.
2. Temperature Control System: It is furnished with a high-precision temperature control system capable of real-time monitoring, control, and display of the temperature and temperature curve within the digestion tank.
3. Pressure Control System: A non-contact pressure control system is available, enabling real-time monitoring, control, and display of the pressure and pressure curve within the digestion tank.
4. Structural Materials: The entire machine housing is fabricated from carbon fiber-reinforced polymer materials, featuring high structural strength.
5. Explosion-proof Cavity: A 316L stainless steel explosion-proof cavity is utilized, possessing multiple layers of anti-corrosion and high-temperature resistant coatings.
6. Cost Reduction: The design eliminates the need for consumables such as explosion-proof membranes and sealing bowls, thereby reducing the cost of later maintenance.
7. User Interface: All are equipped with a 7-inch oversized touch screen, offering a friendly human-computer interaction interface.
8. Software Functionality: The software library stores multiple internationally common standard application methods, allowing users to customize, edit, store, modify, and delete application methods.
9. Electromagnetic Protection: Professional electromagnetic protection design is incorporated, adhering to high-end microwave leakage protection standards.

Working Environmental Conditions:
1. Ambient Temperature: It is advisable to be within the range of 20℃ ± 10℃ to evade the influence of extreme temperatures on the equipment's performance.
2. Relative Humidity: It ought to be maintained below 80% without condensation to prevent damage to the equipment caused by moisture.
3. Ventilation Circumstance: The instrument should be placed on a solid and well-ventilated workstation to facilitate heat dissipation.
4. Power Supply Requirements: An independent and stable power supply should be utilized to preclude the impact of power fluctuations on the equipment's performance.
5. Safety Requirements: The instrument should be kept at a distance from strong magnetic fields and high-power equipment to prevent magnetic field interference and electromagnetic wave leakage.

Precautions:
1. Training: Ensure that the operators have undergone appropriate training to comprehend the correct usage of the equipment and the countermeasures in emergency situations.
2. Equipment Inspection: Before utilization, inspect whether the microwave digestion apparatus is operating normally, including the power supply, microwave system, temperature control, and pressure control systems.
3. Sample Preparation: Ensure that the samples are prepared accurately and avoid the use of flammable, explosive, or microwave-sensitive samples.
4. Appropriate Containers: Employ containers specifically designed for microwave digestion, such as digestion vessels fabricated from polytetrafluoroethylene (PTFE) or borosilicate glass.
5. Sample Volume Control: Do not exceed one-third of the digestion vessel's capacity to avoid excessive pressure generation during digestion.
6. Acid Utilization: Be cautious when using acids and avoid the employment of strong oxidizing acids, such as nitric acid, unless under strictly controlled conditions.
7. Sealing Check: Ensure that the digestion vessels have satisfactory sealing to prevent leakage under high temperatures and pressures.
8. Temperature and Pressure Settings: Set the temperature and pressure parameters correctly in accordance with the sample type and digestion method.
9. Process Monitoring: During the digestion process, monitor the equipment's status periodically to ensure normal operation.
10. Cooling: After digestion, allow the samples to cool naturally within the microwave digestion instrument to avoid pressure variations resulting from rapid cooling.
11. Cleaning and Maintenance: Clean the digestion vessels and the equipment after use and conduct regular maintenance inspections to ensure the long-term stable operation of the equipment.
12. Safety Protection: Wear appropriate personal protective equipment, such as laboratory safety glasses and gloves, during the operation.
