MON73 HIGH PERFORMANCE LIQUID CHROMATOGRAPH

Description

FP640 flame photometer adopts digital display circuit, the measured results are obvious, reading is reliable. The instrument not only retains the medical clinical testing requirements, but also suitable for agriculture, industry for the determination of K, Na element, and have Li salt detection function in patients with psychosis. Flame photometer is emission spectrometry as the basic principle of a kind of analytical instruments. Salt, for example, as for the flame, the flame is yellow, this is because the sodium salt of outer electrons absorbing heat of the flame atom, and the transition to the excitation level, by excitation level back to normal again, electronic to release energy. Characterization of this energy is emitted sodium atoms held by the wavelength of the spectral lines, yellow (5893 a) main wave spectrum. Using the heat of the flame some elements of atomic excitation, and the strength of the instrument measuring the spectral energy, thus the discretion of the judge one element content in the material, this kind of device is called flame photometer.
