Atomic absorption spectrophotometer manufacturer of atomic absorption spectrometer also known as atomic absorption spectrophotometer, according to the material ground state atomic vapor absorption of characteristic radiation to carry out metal element analysis. It can detect trace or trace elements sensitively and reliably.

basic components

Atomic absorption spectrophotometer is generally composed of four parts, namely light source (monochromatic sharp line radiation source), sample atomizer, monochromator and data processing system (including photoelectric converter and corresponding detection device).

There are two main types of atomizer, that is, flame atomizer and electrothermal atomizer. There are many kinds of flames, and the air acetylene flame is widely used nowadays. Graphite furnace atomizer is widely used in electrothermal atomizer, so atomic absorption spectrophotometer, flame atomic absorption spectrophotometer and atomic absorption spectrophotometer with graphite furnace. The atomization temperature of the former is between 2100 and 2400 degrees, and the latter is between 2900 and 3000 degrees.

The main characteristics of atomic absorption spectrophotometer

1. The system is controlled by PC. It can measure the content of elements in most metal materials. The programming of the system adopts the current fashionable visual programming language, so the system has powerful functions and friendly interface.

2. In the process of analysis, zero point and fullness are automatically tracked and calibrated by PC to ensure the measurement accuracy. The operation of the system is simple and quick.

3. The electronic balance and the system are on-line to realize the non-quantitative sampling of the analysis process and improve the analysis speed of the system.

4. The system establishes a powerful database, which is used to store and query the data of analysis results and working curves. It is very convenient to modify the data and add or delete the curves.
