1.The flame photometer is an instrument to measure the intensity of this light spectrum to determine the concentration of the measured element.
2.The flame photometer has the advantage of fast analysis and high sensitivity with little sample consumption. For these reasons, it has been extensively employed in such fields as clinical examination, fertilizer and soil analysis, as well as chemical industry.
3.The flame photometer itself cannot indicate directly the element concentration. First, prepare a standard solution, measure it, and record the results as the standard curve line. Then, measure the unknown solution, read the indication from the photometer, and find the corresponding intensity from the ready standard line.
4.With a simplified air pipeline system and digital-faced circuit, it is easier to operate and to read the result.FP-640 is also applicable to agricultural and industrial measurement of K and Na, and analysis of Li consumption by the psychological patients.
