Working principle of the instrument
The basic principle of photometric anlysis——Lambert- Beer’s Law is applied here: when there is no change in the thickness of the liquid layer, the capability of the solution’s absorbing light is in direct proportion to the concentration of the analyzed material. First a certain amount of sample solution is prepared, under certain conditons, the analyzed material will develop colors, with the light of spefic wavelength, the elements of the material will be determined through their absorbency.
The detection steps are as follows:
Preparing sample→weighing the sample→fusing the sample→leaching the sample→sample developing colors→analyzing the sample with the machine→data processing→report of the analysis results
