Flame Photometer

Introduction of Flame Photometer

A flame photometer refers to a clinical laboratory analytical instrument based on emission spectroscopy, used to determine the concentration of certain metal ions, including potassium(K), sodium(Na), lithium(Li), calcium(Ca) and barium(Ba). The basic principle of the flame photometer is to use flame as the excitation light source, and apply a photoelectric detection system to measure the radiation intensity emitted when the excited element returns from the excited state to the ground state. Judge the element type and content based on its characteristic spectrum and lightwave intensity. It is mainly composed of a light source, a light splitting system, and a detection system. The flame photometer has been widely used in medical and clinical, agriculture, industry, food, etc.


The FP series flame photometer is a newly designed instrument, which uses LPG burning gas as fuel. It has the advantages of small size, simple structure, convenient operation, stability and reliability. The machine adopts a liquid crystal display, keyboard operation, and can store up to 10 points of a standard curve and 200 sets of test data.

Application of Flame Photometer

Flame Photometer is widely used in agricultural fertilizer, soil analysis, cement analysis, analysis and determination of silicic acid industry; clinical laboratory and pathological research of medical and health.

1) Testing of building materials such as cement, glass, ceramics, and refractory materials;

2) Testing of fertilizer and soil;

3) Testing of mining, petroleum, metallurgical and chemical products;

4) Testing of foods such as pharmaceuticals and beverages;

5) Testing of municipal solid waste;

6) Tests for various experiments in scientific research, health, teaching and other fields.
