with phosphorus as internal standard, language as internal standard, test and other elements in the case of relaxation, bypass the impact of the matrix and the third party, so that phosphorus pentoxide aluminum trioxide and other analysis of the micro-improvement, so the test work and the standard of the spectrum of the material can be used on a optical plate to determine the impurity content of the plate by the internal standard method. 3 reagents or materials

Products that have not been calcined at high temperature must be collected. After calcining for 2,6 steps
6.1 Standard sample and sample are respectively ground with 10:2 ratio in the code book grinder, and then put into the lower hole. Fill it and bake it for about 200 degrees for 2 hours, and then take it immediately. The shape of the electrode is shown in the figure below, 46. 0
