Instrument Description : Atomic absorption spectrophotometer important means of quantitative analysis as a routine amount , trace metals and semi-metallic elements , because of its good detection accuracy and high sensitivity , rapid analysis and so on. In all areas of biotechnology, food , geology, metallurgy , building materials , medicine , environment, petrochemicals , agriculture, etc. are widely used . SP-3520AA / SP-3530AA atomic absorption spectrophotometer using expert database information system , to provide you with fast and accurate detection information and detection methods , which greatly reduces the difficulty of the work of analysts , to avoid human error in the operation to ensure that the analysis accuracy. Windows based operating platform Win-AAS workstation software , user-friendly, easy to operate in full compliance with the PC operating practices, without professional training. Main features: First, the total reflection optical system , the whole band achromatic , after adjusting the focus point is good, replace any wavelength , the focal point
Were no longer change . Benefits: a guarantee instrument's measurement accuracy and precision ; 2 replace any hollow cathode lamp
After having to adjust the focus point .
Second, the unique design of the all-titanium burner , combustion smooth , fast thermal equilibrium .
Three , eight lighthouse automatic control system, fully adjustable hollow cathode lamp to the optimum position .
Fourth, the graphite furnace contains three heating modes : Normal temperature , light control power to heat up, when the control power to heat up. Technical parameters: Performance Specifications
