SKZ1044 Digital Flame Photometer

Flame photometer is a relative measurement of the instrument, the concentration value of the sample under test conditions in the same relative value of the concentration of the standard solution.
So before the test, you must first prepare a set of corresponding standard solution. Then the calibration operation, the manual or the standard curve by the instrument, the last to be tested on the test sample, to obtain the concentration value or other data required for calculation.
Principle
Flame Photometer is emission spectroscopy, It utilizes the heat flame itself, stimulate the part of the alkaline earth metal atoms, so that these atoms absorb energy from a first energy level transition, when it falls to a normal energy level, it is necessary to release energy, the energy released have spectral characteristics, that is, in a certain wavelength range.
For example, the salt in a fire, flame yellow, because sodium atoms in the flame down to a normal level when the energy spectrum of the energy released is yellow. People often call this the flame reaction. Different alkali metal or alkaline earth metal in the flame of different colors, each with a different filter, it can be qualitatively tested. The flame intensity is directly proportional to the solubility atoms contained in the solution, which constitutes the basis for a quantitative test. This method is usually called flame photometry, such instruments are usually referred to as flame photometer.
