Auto GDA series automatic graphite digestion instrument
Introduction: For element analysis in samples, traditional manual sample preparation, such as electric heating plates, has poor heating efficiency, slow speed, high energy consumption, poor temperature stability and consistency, and requires a lot of labor and affects the next step of AAS, AFS, The accuracy and precision of the analysis results of ICP and ICP-MS analytical instruments. Sage Scientific Auto GDA series full-automatic graphite digestion instrument adopts the principle of wet digestion, and automatically completes the test steps of acid addition, mixing, capping, cap removal, temperature-programmed digestion, acid removal, cooling and constant volume, and the whole process is fully realized. Automatic and unattended, up to 72 samples can be processed automatically in one batch. Auto GDA series automatic graphite digestion instrument conforms to the wet digestion method of Chinese national standard and the digestion method of American EPA standard. It is the best choice for the pretreatment of heavy metal detection in samples. Features: 1. Dosing system Fully enclosed Teflon magnetic suspension mechanical arm, corrosion resistant Double peristaltic pump + syringe pump dosing combination method Multiple reagent channels can add corrosive reagents (including hydrofluoric acid and hydrofluoric acid solutions) Digestion reagent delivery system is resistant to strong acids and alkalis, and the dosing speed is adjustable Under the same method, the type and amount of acid added can be different for the betting digestion tank. 2. Heating system Double heating module design, surround heating, program heating and cooling Excellent temperature consistency between sample positions, temperature control accuracy is plus or minus 0.1℃, and the temperature difference between holes is plus or minus 1℃@150℃ Intelligent PID temperature control system 3. Shaking system Digestion tube cap is automatically added and removed The host is equipped with a digestion pipe rack and a motor lifting system, which can automatically lift and oscillate 4. Constant volume system Ultrasonic sensor constant volume system Syringe pump adds constant volume solution 5. Ventilation system Instrument standard ventilation system Fan anticorrosion fan exhaust pipe HEPA filter 6. Software system WiFi connection, computer control Chinese and English software, graphical interface, conducive to customer operation Record the data and steps in the process, and automatically generate experiment logs and experiment reports Built-in a variety of EPA, GB methods, and can freely set digestion and other pre-processing steps Store almost unlimited digestion and pre-processing programs
