Three lamp holder single graphite furnace atomic absorption spectrometerProfessor Wu Tingzhao and Professor Chen Lianyuan, who developed this instrument, are both experts in the atomic absorption industry in China for many years, with experience in developing various types of instruments. They have combined their years of experience to improve the sensitivity of element testing in atomic absorption spectrometers to a new level, and their technology has enabled the sensitivity of flame atomic absorption to reach a certain level. Due to the multiple application methods of this type of spectrometer, a new laboratory can be established with just one instrument, which is suitable for China's national conditions and very suitable for analytical research work in various units.

1. Application in theoretical research

Atomic absorption can be used as an experimental method in physics and physical chemistry to determine and study some basic properties of substances. The electric atomizer is easy to control the evaporation and atomization processes, so there are many advantages to using it to measure some basic parameters.

The activation energy, gaseous atomic diffusion coefficient, dissociation energy, oscillator intensity, broadening of spectral line profile, solubility, vapor pressure, etc. of some elements leaving the body measured by an electric heating atomizer.

2. Application in Elemental Analysis

Atomic absorption spectroscopy analysis, due to its high sensitivity, minimal interference, and simple and fast analytical method, has been widely used in various fields such as industry, agriculture, biochemistry, geology, metallurgy, food, and environmental protection. Currently, atomic absorption has become one of the powerful tools for metal element analysis and has been used as a standard analytical method in many fields.

At present, atomic absorption method has been used to determine more than 70 elements in geological samples, and most of them can achieve sufficient sensitivity and good precision. Atomic absorption method is now widely used for the analysis of various trace elements in steel, alloys, and high-purity metals.

Atomic absorption is becoming increasingly widespread in food analysis. There are satisfactory atomic absorption analysis methods for over 20 elements in food and beverages. The analysis of essential and harmful elements in biochemical and clinical samples has now been carried out using atomic absorption spectroscopy.

There have been increasing literature reports on atomic absorption analysis of metal elements in petroleum products, ceramics, agricultural samples, drugs, and coatings in recent years. The analysis of trace metal elements in environmental samples such as water and atmosphere has become one of the important fields of atomic absorption analysis. Indirect atomic absorption spectroscopy can also be used to determine certain non-metallic elements.
