AAWin software

AAWin Software is a powerful and intuitive software product designed to allow control and data acquisition from the A3 series Atomic Absorption Spectrometer.
The AAWin software allows the Analyst to control all aspects of their analytical method whilst providing an extensive range of tools for data collection, storage, and interpretation.

Light source

Automatic 8 Hollow Cathode lamp turret controlled and optimized by the AAWin software. Can control Operating lamp current and warm-up lamp current to eliminate drift commonly associated with lamp warming.

Background correction

D2 lamp background correction system fitted as standard to all configurations. High-energy D2 lamps and adjustment beam splitter mirror with the AA-Win 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.

Optical system

High-precision minimal optics ensures maximum light throughput to the computer-controlled Czerny-Turner monochromator.

Autosampler

A universal autosampler is available as an optional accessory. It is on the front of the A3 instrument to automatically introduce standard and unknown samples to the atomizer for analysis.

Flame mode:

The flame atomizer offers three flame options:

Air/Acetylene:
The high sensitivity (Cu 2ppm >0.280abs) is due to the efficiency of the fixed-position glass nebulizer fitted as standard. An acid-resistant replacement is available as an option.

N2O/Acetylene:
These flame configuration measure elements are prone to ionization such as Aluminum, Tin, Titanium, Calcium, Vanadium, and Molybdenum. The software AAWin3.0 will control switching from Air/Acetylene to N2O/Acetylene becoming flame-off

Air/Propane (LPG)

Due to the low temperature of the flame, it is ideal for analyzing alkali metals such as Potassium, Sodium, and Lithium, especially when used in the emission mode. Some remote areas of the world have difficulty obtaining Acetylene gas of a high enough purity to operate the flame correctly, LPG can give a real alternative and offer comparable results for most elements throughout the wavelength range.

Principle Metal Content A3F Persee:

A3F is a highly sensitive analytical technique that can detect trace amounts of elements in a sample. The elements are heated and atomized in the pyrolytic graphite furnace, and become atomic vapor in the ground state, which selectively absorbs the characteristic radiation emitted by the hollow cathode lamp. Within a certain concentration range, its absorption intensity is proportional to the content of the element to be tested in the test solution.
