4 Sampling
4.1 test sample
Made by GB/T 6678 provisions.
4.2 Sample
Take appropriate laboratory sample is placed within the finely crushed porcelain mortar, with a pore size of φ75μm test sieve (in line with GB/T 6003.1 in
R40/3 series) screening. Take 15g ~ 20g sample size of less than 75μm, and placed in an oven, 105 ℃ drying 2h, taken into a dry
It is cooled and set aside.
5 vanadium, titanium, tungsten, molybdenum, silicon, aluminum, barium, calcium content measurement --- X-ray fluorescence spectrometry (XRF)
5.1 Principle
Atomic elements excited by high-energy radiation caused by inner-shell electron transition, and emit X-rays with a certain characteristic wavelength, root
According to the measured spectral wavelength and intensity of elemental qualitative and quantitative analysis.
