SP-3880AA is innovative in key technologies such as automatic compensation of graphite furnace resistance changes, transverse variable AC magnetic field Zeeman background correction technology, and self-priming background correction technology. It has applied for 7 invention patents (5 of which have been approved for initial review) and 3 utility model patents (including the patent number "A graphite furnace head conducive to precise clamping":. 6 certificate number 1270983).
2. This product is designed with an integrated graphite furnace flame atomic absorption system, avoiding mechanical switching between graphite furnace and flame modes. It is easy to operate and has AC/DC Zeeman background function, which can effectively detect small signals of high background samples and directly detect high-temperature elements. It has a wide range of application prospects.
3. This product has achieved the series structure technology of total reflection double atomizers, switch type graphite furnace DC heating power supply technology, and AC/DC Zeeman background correction technology, all of which are pioneering in China.
SP-3880AA not only achieves the integration of transverse variable AC magnetic field and DC magnetic field Zeeman background correction, but also simultaneously performs these two types of magnetic field Zeeman background correction, making the system not only have the advantages of a constant magnetic field but also the advantages of an alternating magnetic field. At the same time, it is convenient to optimize the method in practical applications and provides conditions for in-depth research on Zeeman background correction. This technology is an international first.
