Laboratory use specifications and test methods GB/T 6682 Analysis
GB/T 14506.1 Silicate rocks - Part 1. Determination of water adsorption
Principle 3
Sample anhydrous lithium tetraborate melted ammonium nitrate as the oxidant, plus a small amount of lithium fluoride and lithium bromide as flux and mold release agents. Sample and
Mass flux ratio of 8. The fusion machine at 1150 ℃ ~ 1250 ℃ melted into glass samples. In the X-ray fluorescence spectrometer
The measure, in addition to nickel, copper, strontium and zirconium with Compton scattering line as internal standard calibration matrix effect, the rest of the elements are analyzed theoretical coefficient α
Absorption correction between elements - enhancing effect, the amount of primary and secondary component is calculated based on the fluorescence intensity.
4 Reagents
Unless otherwise stated in this section are consistent with the use of analytical reagent and GB/T 6682 analytical laboratory use in the analysis.
4.1 anhydrous lithium tetraborate. Burning 2h at 700 ℃.
4.2 lithium fluoride. bake at 105 ℃ 2h ~ 4h.

4.4 lithium bromide solution (15g/L).
5 Instruments
5.1 platinum - gold alloy crucible (95% Pt 5% Au), Specifications. 30mL. If the sample in the crucible directly after melt molding, the bottom of the crucible requires
Smooth inner wall surface. Specifications. the upper end of the inner diameter of 45mm, the lower end of the inner diameter of 33mm, height 25mm.
5.2 platinum - gold alloy casting (95% Pt 5% Au), Specification. upper inner diameter 34mm, the lower end of the inner diameter of 32mm, height 3mm. Mold material
Thickness of about 1mm, making it difficult to deformation. Mold regularly with a particle size of 14μm of emery paste polishing glass sheet easily peeled from the mold
Without cracking.
