Atomic Absorption Spectrometer

Instrument introduction

AAS6000 Series are Single Beam Atomic Absorption Spectrometers controlled and data processed by external computer and internal CPU chips. AAS6000 can be used to measure the concentration of macro, micro and trace metal elements and half-metal elements in various kinds of substances. 
Atomic absorption spectrometry is a technique exploiting the fact that atoms at ground state may absorb the radiation of characteristic wavelength. As is known, the atoms are usually at ground state. For each element, the amount of energy required for an atom to transit from ground state to excited state is specific, and in general, is called characteristic wavelength. The Atomic absorption spectrometry typically makes use of hollow cathode lamp as the light source to emit the characteristic wavelength of a particular element. When the light passes through the atomic vapor, it is absorbed by the vapor. The concentration of the element can then be determined through the calculation of the absorption rate. 
AAS6000 is provided with three reading methods Continuum, Retention and Peak Height for measuring absorbency, density and emission intensity. It has three signal modes: Atomic Absorption, Background Absorption and Background Correction Absorption, The reading time ranges from 0.5 s to 99s. AAS6000 include 8 computer controllable hollow cathode lamp holders. All working conditions of the instrument such as lamp number, lamp current, negative high voltage, working wavelength, slit, burner location, ignition/extinction and adjustment of burning ratio can be set by keyboard input. The functions of the instrument include automatic gain/ automatic zero, background correction, automatic energy balance, automatic peak location/wavelength scan, and automatic peak location on basis of the retrieval of peak values. All the readings, measurement results, calibration curves and operation conditions can be saved or printed out.
