Product Description	The A3G Atomic Absorption Spectrometer is a high-performance automatic instrument with graphite furnace atomization mode. It adopts multiple safety protection measures. Except for the power switch, all other controls are completed by computer, which not only ensures the reliability of the instrument, but also protects the safety of operators and equipment. A universal auto-sampler for both flame method and graphite furnace make the analysis more convenient and reliable.
Features	◆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 3.0 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. ◆Graphite furnace temperature control The temperature of the transversely heated graphite tube is accurately controlled by means of a precision feedback system and has been designed to reduce analytical problems normally associated with this type of technique. ◆Graphite tube Pyrolytically coated graphite tubes are used as standard and are manufactured to improve performance as well as increase the analytical life. Platform graphite tubes are supplied as standard and will accept volumes up to 50ul. Non-platform graphite tubes are also available as an optional extra. ◆Safety features Argon gas pressure sensor Water flow senor Over temperature sensor Broken graphite tube protection
Principle	A3G 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.

Application	A3G can be used for a wide range of applications including environmental science, agriculture, food science, pharmaceuticals etc. ◆Environmental science A3G 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 A3G 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 A3G 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 A3G 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.
