IAFS11001 Peristaltic pump atomic fluorescence spectrophotometer
● Light source: Adopting a concentrated pulse control method, dual channel or single channel measurement can be freely selected to improve work efficiency.
● Sampling system: A fully automatic built-in dual sequence sampler (imported sampler is used for precise quantification of both sample and reducing agent injection) is used for the sampling system device. (Original imported sampler from the United States).
● Configure a new polar coordinate disc type automatic feeder with a single sample tray of no less than 160 positions to achieve fully automatic analysis and detection, and improve work efficiency.
● The argon hydrogen flame observation window has a dual function design, which allows for direct observation of the flame and fully enclosed measurement.
● With an imported dedicated four position valve that switches flow paths, has a long service life, and is not prone to aging.
● Accurately control the volume of the solution for reaction, including the volume of reducing agent, single point automatic standard curve r>0.9995, automatic cleaning after high concentration measurement of the sample, and automatic dilution and measurement of high concentration samples.
● Mercury lamp stabilization device with atomic fluorescence measurement.
● Gas-liquid separator: two-stage gas-liquid separation, all quartz material control.
● A trap device with hydride generation atomic fluorescence measurement for harmful elements in exhaust gas: Through adsorption and chemical treatment of toxic elements, the laboratory is not easily contaminated and works together with exhaust devices to ensure the safety of operators.
IAFS11002 Injection pump atomic fluorescence spectrophotometer
