High definition camera with real-time image display function, which can help users observe the sample digestion status in real time. Color sensor, for digestion experiments with color changes, intelligently determines the endpoint of digestion.

fast and efficient

Three dimensional surround high-temperature heating, small temperature difference between holes, more uniform digestion

PID intelligent temperature control, accurate, stable, and uniform, with a heating chamber module design, maximum processing capacity of 60 bits per batch, maximum working temperature of 240 ℃, temperature control accuracy of ± 0.1 ℃, uniform heating of all parts of the sample, temperature difference between pores within 1 ℃, and more uniform digestion. Automatic temperature calibration, if there is a temperature deviation, no need for professional personnel or cumbersome steps, one click calibration, easy to operate.

High precision peristaltic pump+10 channel electric injection valve, making liquid addition more efficient

The reagent is added through a high-precision peristaltic pump, with a liquid addition error of less than 1% (50mL). 9+1 reagent channels, all internal pipelines are made of PTFE material, suitable for adding all reagents, including perchloric acid, hydrofluoric acid, gao meng suan jia, etc., to ensure the diversity and integrity of digestion schemes.

Reagent management system, residual monitoring, making every experiment "effortless"

Equipped with a 6-digit reagent management system as standard, the remaining amount of reagents is monitored in real-time. When the amount of reagents is insufficient, an alarm prompt is triggered to avoid experimental errors caused by insufficient reagents and improve work efficiency. Each reagent bottle is equipped with an air filtration device to prevent impurities in the air from contaminating the reagents.

safe and reliable

The whole machine is corrosion-resistant, durable, and the reliability of the instrument is improved

The instrument experimental platform is made of polytetrafluoroethylene sheet material processed as a whole, and the graphite blocks are coated with a special high-temperature and corrosion-resistant coating. All components in contact with acid gas, such as the mechanical arm and exhaust fan, are designed with anti-corrosion measures to ensure long-term reliable operation of the instrument.

Wi Fi remote connection and control, away from high temperatures and acid mist, more comfortable and safe

Through Wi Fi communication technology or RS 232 serial port connection, remote monitoring and control can be achieved using a computer, achieving full automation and unmanned operation, keeping experimental personnel away from high temperatures and chemical reagent hazards.

Powerful and convenient software assistant, user-friendly interface, easy to operate

Full Chinese operation interface, modular design of digestion solution, direct drag and drop for setting; The heating curve and experimental progress can be displayed in real time, and the digestion status is clear at a glance; Easy operation such as reagent management and method establishment, eliminating repetitive and cumbersome operating procedures, saving laboratory personnel work time, and improving work efficiency.

Application Examples

Detection of cadmium (Cd) content in wheat

Refer to GB 5009.15-2014 "National Food Safety Standard - Determination of Cadmium in Food"

weighing

Grind the wheat sample into powder using a grinder, accurately weigh about 1g of the sample, and record it. When transferring samples into the digestion tank, try to send them to the bottom of the tank to avoid hanging on the wall.

resolve

Weigh the sample and place it in a digestion tank, record it, place it on a graphite furnace, run the program, automatically add the digestion acid: 5mL nitric acid+0.5mL perchloric acid, shake at full power for 2 minutes, and perform digestion.

determination

Use graphite furnace atomic absorption spectroscopy to determine the Cd content in the sample, with an analysis line of 228.8nm, a working current of 2mA, a negative high voltage of 300V, and an injection volume of 10 μ L. The standard curve has a correlation of 0.99768.

result

The RSD of 6 wheat samples determined by graphite furnace method was 3.9%, with good parallelism, indicating small temperature differences and high uniformity of digestion. The recovery rate of spiked samples is 93%~98%, and there is basically no matrix effect, indicating that the digestion is basicwan quanThe entire pre-processing process has no impact on the detection. The recovery rate of quality control samples is 101%~103%, and the test values are all within the uncertainty range, indicating accurate results.
