Basic structure of atomic absorption spectrometer
1. Light source: produces light with characteristic wavelengths of the analyzed elements. The common ones are hollow cathode lamp (HCL), stepless discharge lamp (EDL) and ultralight (UltrAA Lamp).
2. Atomizer: convert the analyzed elements in the sample into free atoms in proportion. The energy required is usually heating. Commonly used methods are air-acetylene, nitrous oxide-acetylene flame and electric heating. Atomized atoms absorb light.
3. Optical system: guide the light into the atomic vapor and guide the outgoing light into the monochromator.
4. Monochromator: Separate the characteristic wavelength of the specific analyzed element produced by the element lamp from other non-characteristic wavelengths.
5. Detector: A photosensitive detector (usually a photomultiplier tube) accurately measures the light intensity and converts it into an electrical signal
6. Electronic circuit: converts the corresponding value of the detector into a useful analytical measurement value.
1. Completely controlled by PC, can flexibly select the flame and graphite furnace atomizer (optional);
2. Eight light stands can be changed automatically and preheat the eight element lights meantime as well as optimize the working condition of the hollow cathode lamp;
3. Position adjusting: the best height of the flame burner and can automatically set the front and rear positions;
4. Fully automatically wavelength scanning and peak searching;
5. Completely safety chains protection equipment: the function of warning and automatic safety protection towards the wrong burner, leakage of the gas, under voltage of air and the abnormal flameout;
6. lamp and self-absorption background regulation;
7. Data processing: super strong database, possesses more than 500 data self-storage and cut-off storage function, can store the analyzed result with the form of EXCEL and the testing method and the result can be randomly called;
8. Measuring method: flame absorption method and emission method;
9. Result printing: parameter printing, data result printing and diagram printing;

Process of Flame Atomic Absorption Spectrometer
1. Radiation from the specific light source is focused on the atomic vapor in the flame.
2. The radiation then enters a monochromator, which isolates the line of interest.
3. The light is then measured by a photomultiplier tube (detector).
4. The signal is then processed and the computer system prints the output on screen.
