A3F

A3F – The instrument is equipped with a flame atomiser only. The positioning of which is fully controlled by the embedded com-puter system and AA-Win 3.0 software. Three flame options are available to the user with the Air/Acetylene being the standard con-figuration. 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 of elements. All three flame configurations offer coded burner for full safety protection.

◆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. Operating lamp current and warm-up lamp current can be individually controlled to eliminate drift commonly associated with lamp warming.

◆Background correction
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 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 com- ponents are required and optical alignment is very simple. Self-Reversal can be used for any element at any wavelength making it extremely versatile.

◆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 which is conveniently mounted 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. The flame can be easily set from blue lean flame through stoichiometric to fuel rich by means of computer control.
N2O/Acetylene:
This flame configuration is used to measure elements less prone to ionization such as: Aluminum, Tin, Titanium, Calcium, Vanadium and Molybdenum. Switching from Air/Acetylene to N2O/Acetylene to Flame Off is fully controlled by the AAWin3.0 software.
Air/Propane (LPG)
Due to the Iow 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.

◆Safety features
Pressure monitoring for all gases
Burner Identification
Flame sensor
Drain trap level sensor
Gas leak detector
Over pressure in premix
Safety cut off switch

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.

A3F can be used for a wide range of applications including environmental science, agriculture, food science, pharmaceuticals etc.

◆Environmental science
A3F can be used to analyze soil, water, and air samples for the presence of heavy metals such as lead, mercury, and cadmium. This information is critical for understanding the impact of human activity on the environment and for monitoring compliance with environmental regulations.

◆Agriculture
A3F is used to analyze soil and plant tissues for the presence of essential elements such as nitrogen, phosphorus, and potassium. This information is important for optimizing crop yields and for ensuring that plants have the nutrients they need to grow.

◆Food science
A3F is used to analyze food samples for the presence of toxic elements such as arsenic and lead. This information is critical for ensuring that food products are safe for human consumption.

◆Pharmaceuticals
A3F is used to analyze drug formulations for the presence of impurities and contaminants. This information is important for ensuring that drugs are safe and effective for human use.
