Atomic Absorbtion Spectrometer
- Persee - A3 AAS
- Easy to use, complete software control
- Integrated safety precautions for user protection
- Flexible configuration for a wide array of industrial apps
The A3 Atomic Absorption Spectrometer 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. Three flame options are available to the user with the Air/Acetylene being the standard configuration. This flame can be used for nearly all standard elements while the N2O/Acetylene and the Air/LPG (natural gas) are available as an option for the more demanding elements. All three flame configurations offer coded burners for full safety protection.
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 flame and graphite furnace can be changed over by a simple selection in versatile AA Win Pro software.
Key Features

- Flexible configuration for a wide array of industrial apps
- Time-saving high-speed analysis
Features and Functions
PC System is used to control the instrument. Preinstalled AA-Win Pro software, user manuals, cookbook and Windows 7 Professional operating system.
AA-Win Pro software provides full control of the instrument and autosampler with easy method change for each technique.
Automatic 8 Hollow Cathode lamp turret controlled and optimized by the AA-Win Pro software. Operating lamp current and warm-up lamp current can be individually controlled to eliminate drift commonly associated with lamp warming.
D2 lamp background correction system fitted as standard to all configurations. High energy D2 lamp and adjustable beam splitter mirror are optimized by the AA-Win pro software.
Self-Reversal background correction system fitted as standard to all configurations. The high-performance background system uses the same hollow cathode lamp as installed for the analysis. Minimum extra components are required and optical alignment is very simple. Self Reversal can be used for any element at any wavelength making it extremely versatile.
High precision minimal optics ensures maximum light throughput to the computer-controlled Czerny-Turner monochromator.
A universal autosampler is available as an optional accessory that is conveniently mounted on the front of the A3 instrument.
Absorption and Emission modes are standard features in the AA-WinPro software as well as peak height, peak area, and sequential and manual integration modes.
