. This standard set main content and suitable scope glass is industrial the principle that dolomite chemistry composition analyses, use reagent, instrument, analyse measure and result processing. This standard applies to glass industrial the chemical composition analysis of dolomite. 2. The preparation sample of sample must be had representative with uniformity, without interfuse of exotic foreign matter, through division, end up with make an appointment with 20g sample, abrade in agate earthen bowl come to pass bore diameter entirely 150 μ M (100 eye) sieve, install next reserve in metage bottle. 3. Analytic method 3. 1 general provision 3. 1. Place of same class status lists different analysis method in 1 standard, can choose according to particular case, if produce controversy. It is with the first kind of method accurate. 3. 1. 2 answer with quantity of analytic balance feeling for 0. 0001g, balance and weight used on a balance should have desired result regularly. "Constant weight " the department shows the difference that says twice to weigh continuously is more than 0. 0002g. 5. 1. 3 should be passed with instrument and measuring implement corrective. 3. 1. 4 analysises sample should be in in oven 105 - above of 1h of 110 ℃ drying, refrigeration comes room temperature, undertake metage. 3. 1. 5 analysises should be distilled water with water or go ionic water; Place should be an analysis with reagent pure or super grade is pure; The reagent that is used at demarcate solution should be fiducial reagent.
