Introduction：
Flame Photometer, based on atomic emission (flame photometry), measures the concentration of alkali and alkaline-earth metals such as potassium, sodium, calcium and lithium in solution. Widely used in agriculture, soil testing, cement, ceramics and glass industries....
The flame photometer is a relative measuring instrument based on the principle of atomic emission spectrometry (flame color reaction), mainly used to determine the concentration of alkali metal and alkaline earth metal elements (such as potassium, sodium, calcium, lithium, etc.) in solutions.
The concentration value of the tested sample is the relative value with respect to the concentration of a standard solution under the same test conditions. Before testing, a set of standard solutions must first be prepared, then a calibration operation is carried out to draw a standard curve manually or via the instrument, and finally the tested sample is measured to obtain its concentration value or other required calculation data.
It can be widely used in environmental monitoring, agriculture and fertilizer industry, food industry, chemical manufacturing, medical and clinical diagnosis, geology, mining and new energy industries, and other fields with sample pretreatment requirements.
