Features
1.Adopts total reflection optics and all-wavelength achromatic design. Equipped with automatic wavelength scanning and peak search functions to ensure accurate positioning and improve the performance of atomic absorption spectrometer.
2.The uniquely designed all-titanium burner provides stable flame combustion and rapid thermal equilibration, making it ideal for high-throughput flame AA spectroscopy applications.
3.Automatically adjusts negative high voltage, lamp current, and element lamp position to maximize light energy. Equipped with automatic gas leakage and flame extinguishing protection system to ensure safe and reliable operation.
4.The 8-lamp turntable (optionally can be equipped with 2 high-performance lamps) is fully automatic and can accurately adjust the hollow cathode lamp to the optimal position. The position of specific element lamps can be pre-set and the function of operation/preheat lamp can be freely set, greatly reducing the preparation time of element lamps.
5.The system can be upgraded to a graphite furnace atomic absorption spectrometer, which increases the flexibility of trace element analysis and extends the application range of the instrument from routine testing to ultra-trace detection.
