Atomic Absorption Spectrophotometer (AAS)
At Labindia, we manufacture state-of-the-art Spectrophotometers ranging from fully automatic ones to UV-VIS Spectrophotometers.The AA8000 Atomic Absorption Spectrometer is a high performance automated instrument designed to meet the requirements of the modern laboratory. Due to its versatility and performance AA8000 can be used for a wide range of applications including: Agriculture, Clinical, Environmental, Food, Metal, Mining and Petrochemical. The AA8000 Atomic Absorption Spectrophotometer is a true double beam with sealed and vibration free optical system, having Czerny-turner Monochromator with Holographic grating (1800 lines/mm).
The instrument is available with a flame atomiser and graphite furnace. Three flame options are available namely – Air/Acetylene, N2O/Acetylene and Air/LPG (Natural gas). This AAS system can be fully automated via either our Universal Auto-sampler OR a Random Access Auto-sampler. Hydride analyser is also available can also be FULLY automated. The instrument is FULLY controlled via our ‘user-friendly’ software AAWin. With more than 1000 units sold World Wide the AA8000 atomic absorption spectrophotometer is used in many locations and for many applications and well accepted as a High Specification and reliable system.
