XT-9900A Intelligent Microwave Digestion / Extraction Instrument

In modern analytical chemistry, the analysis of elements that are closely related to human health, environmental protection, material composition, mineral content, food safety, etc. has attracted more and more attention and attention. As we all know, the analysis process of inorganic elements mainly includes two parts: sample preparation and instrument detection. Because modern instruments (AFS, AAS, ICP-AES, ICP-MS, etc.) and their testing methods have been developed relatively mature, the measurement process can be completed in minutes or even seconds, and the measurement sensitivity and precision are both Satisfactory. Therefore, the key to determining the speed and quality of sample analysis during the entire analysis process is sample preparation techniques and methods. However, the classic sample processing methods such as acid hydrolysis, alkaline melting and dry ashing commonly used in existing laboratories not only exist in time-consuming, large energy consumption, high reagent usage, sample cross-contamination, and target elements (especially As, Hg, Pb, Se, etc.) is not sufficient for loss of volatilization, etc., and the acid mist generated will also pollute the environment and endanger operators. For this reason, people have been trying to find some that can overcome the deficiencies of these classic sample preparations, and in 1986, the idea of using microwave for sample pretreatment was first proposed. As soon as the idea of introducing microwave energy into sample pretreatment was proposed, the relevant high-pressure or atmospheric pressure microwave digestion / extraction methods, technologies and instruments have been widely recognized and unprecedentedly developed.

In order to further adapt to and meet the needs of users and the market, according to user suggestions and our long-term practice and summary, the company retains the excellent characteristics of the original XT-9900 intelligent microwave digestion / extraction instrument, in the appearance of the instrument, interface settings, and digestion tank materials Improvements and upgrades have been made, and the "XT-9900A" intelligent microwave digestion / extraction instrument has been introduced to further improve the stability and safety of the product.

Technical index

Microwave feed mode: true non-pulse type variable frequency microwave power adjustment;

Dual CPU monitoring: The dual CPU interactive monitoring mode can automatically and accurately control temperature and pressure, and the microwave input power can be adjusted automatically. The unique pressure rapid rise suppression function can prevent excessive pressure fluctuations; ensure the digestion safety of samples with high organic content;

Microwave power / frequency: arbitrarily adjustable within 1000 W (50 ~ 100% P); frequency 2450 MHz;

Number of sample digestion: 1-6 samples can be digested at the same time;

Temperature and pressure control: maximum working temperature, 250 ℃ (temperature control accuracy, ± 1 ℃); non-contact pressure control range, 0.1 ~ 5.0 MPa (pressure control accuracy, ± 0.01 MPa), maximum pressure resistance up to 6 MPa; The instrument uses the safest non-contact automatic pressure control mode;

Operating procedures: 9 operating procedures (methods) can be set, modified, stored and recalled at one time. Each method can set 9 operation steps (work steps), the time of each operation step is set between 1 ~ 9999 s, after each step is set, it will automatically switch; adjusting "zero" or "full scale" automatically complete Keep the pressure constant for each digestion.

Microwave "shock" function: The unique pause / start and microwave "shock" design can be turned on at any time to check or continue operation. "Shock" function: When the pressure rise rate is too fast (³0.2 MPa / s), the instrument automatically cuts off the microwave. After the pressure drops, the microwave automatically feeds in, which greatly improves the safety and convenience of operation.

Multiple safety guarantees: Nine layers of active and passive safety guarantee measures, including : 1) Pressure-resistant tank material: Polysulfone material outside the tank with PPS liner, inner tank made of polytetrafluoroethylene; 2) Overpressure alarm: available Pressure automatic matching control, pressure real-time display, pressure rise rate automatic limit ("shock" function) and automatic overpressure alarm; 3) Overheating protection: When the cabinet or outer tank overheats, the instrument automatically alarms and stops microwave radiation; 4) different Sound detection: When an abnormal sound is made in the furnace cavity, the instrument will alarm and automatically cut off the microwave; 5) Failure self-test alarm: Any failure of the instrument can automatically detect, alarm and prompt the cause of the failure; 6) Forcible suspension: Once a safety problem occurs At this time, the microwave generation can be forcibly stopped by two methods: "emergency stop button" or "remote remote control"; 7) air hole pressure relief: when the gas pressure in the digestion tank is too large, the gas is discharged from the air hole; 8) the explosion-proof membrane is reduced Pressure: When the pressure is greater than the maximum pressure limit and the vent hole is too late to vent, the explosion-proof membrane on the side of the sealed bowl breaks and decompresses; 9) Safety cover: high-strength PC board outside the furnace chamber door Cover, ensure the absolute safety of the operator.

Easy operation: full menu interface, convenient setting of working parameters; real-time diagnosis and prompting of error information, simple and clear operation; opening / closing the digestion tank, without any auxiliary tools or procedures, opening / closing is easy and simple.

Others : power supply, AC220 V ± 10%, 50Hz; power: 1360W; furnace cavity volume, 34 L; overall dimensions; 570mm * 510mm * 520mm; weight: 25 Kg.

Performance characteristics

Power control: true "non-pulse variable frequency microwave power adjustment" function.

High intelligence: dual CPU monitoring, intelligent temperature and pressure control; wireless remote control, anti-microwave and visible light interference, furnace overheating protection, and self-diagnosis of abnormal conditions and display error information;

Program control: 9 operation programs that can set parameters (pressure, time and power) arbitrarily. The instrument can automatically convert the microwave power input according to the set parameters to achieve automatic temperature and pressure control.

Multiple safety guarantees: The instrument is equipped with up to 9 kinds of safety protection functions, including the first automatic identification and protection of pressure surge program (ie, "shock" function), abnormal sound detection protection, furnace overheating protection, and enhanced high-pressure outer tank , System fault self-test alarm function, manual or remote emergency stop switch, pressure relief in the inner tank vent, decompression of explosion-proof membrane and high-strength safety cover.

Easy to operate: The system will self-test when the instrument is powered on; the pressure zero and full scale are automatically adjusted at one time, accompanied by a buzzer prompt; if the instrument is abnormal, it can automatically diagnose and display error information.

New working interface: menu-based interface, manual or remote control operation, sound prompt, improper operation is automatically prohibited, easy to learn.
