Advantages over analogues: Benefits: Maximum automation of analysis and management tool. The most affordable price. Automated turret 6 hollow cathode lamps. Robust design of the optical system, providing a high resistance reading spectrometer at room temperature changes and vibrations. Most unique integrated design that combines in one compact package all modules AA spectrometer optical system, spraying flame and graphite, graphite atomizer power supply and electronic control unit. The use of reliable and durable titanium atomizer and burner allows you to work with high-temperature flames and prevent corrosion and oxidation of these details. High-resolution diffraction grating (1800 lines / mm) provides high detection sensitivity with excellent spectral resolution. Optimized methods for the correction of non-selective absorption (background): deuterium method and the self-absorption of spectral lines can significantly reduce the error in the analysis of samples of complex composition. Multi-stage automatic safety system: the control-current hollow cathode lamps, alarm and protection of the pressure drop and leak gas, defense graphite atomizer from overheating. Hydride generator (option) for highly sensitive analysis of elements such as Hg, As, Se, etc. Autosamplers (optional) for graphite and flame atomizers. To fully automated analysis using an autosampler, including automatic preparation of calibration solutions and the addition of the modifier. Automatic fast switching flame and graphite atomization (model AA-7003).
