Model AAS-4000 Atomic Absorption Spectrophotometer AAS-4000 is a high performance automated instrument designed to meet the requirements of the modern laboratory. Due to its versatility and performance it can be used for a wide range of applications including: Agricultural, Clinical, Environmental, Food, Metal, Mining, Geological, Petrochemical, and Pharmaceutical. The instrument is equipped with a Graphite Furnace Atomizer only. The graphite head is fixed into the optical path to maximize performance and eliminate drift. The temperature of the transversely heated graphite tube is accurately controlled by means of a precision feedback system. Pyrolytically coated platform tubes are supplied as standard to improve the performance and eliminate many analytical problems associated with this technique. The Fully Automatic Fast Sequential Multi-Element Analysis Graphite Furnace Atomic Absorption Spectrometer system is equipped with an EIGHT Hollow cathode lamp motorized turret Atomic Absorption Spectrophotometer. The graphite furnace heating cycle, all electronic functions, analytical data and gases are fully controlled via the AAWin3 Software for maximum safety and optimum performance.
