In scientific experiments and industrial production, it is very important to accurately measure the concentration of gases. Among them, a flame photometer is a commonly used gas concentration measurement device, which can infer the concentration of gas by measuring the color of the flame.
FP6432 flame photometer is a high-precision gas concentration measurement device designed based on the principle of atomic absorption spectroscopy. It works by using the measured gas to produce a specific absorption spectrum when irradiated with a specific wavelength of light, and by measuring the intensity of this absorption spectrum, the concentration of the measured gas can be inferred.
The FP6432 flame photometer is an analytical instrument designed and manufactured based on the basic principles of emission spectroscopy. The flame is used as the excitation light source, and the flame photometer is an instrument that uses emission spectrometry to analyze, the flame is used as the excitation light source, and the photoelectric detection system is applied to measure the radiation intensity emitted by the excited element when it returns to the ground state from the excited state. Specifically, when the atoms or ions in a sample are excited by a flame, they emit spectral lines of characteristic wavelengths. Based on these characteristic spectra and the intensity of light waves, the type of element and its content can be determined.
The flame photometer itself cannot directly derive the absolute concentration of the element to be measured, but is quantitatively analyzed according to the Roman gold formula. This method is done by introducing an appropriate analytical specimen into a flame, relying on the thermal and chemical effects of the flame (1800-2500) to evaporate, ionize, atomize, and excite the luminescence.
