The specialized flame photometer for soil and fertilizer analysis is an analytical instrument designed and manufactured based on the fundamental principles of emission spectroscopy. It finds extensive application in the analysis and determination of agricultural fertilizers, soils, cement, ceramics, and silicate industries, as well as in pathological research within medical and health sectors. This flame photometer utilizes liquefied petroleum gas as its fuel.
