3 General provisions
The water used in this standard ion chromatogram is pure water with a resistivity value of not less than 18Mohm · cm, and the other reagents and water used are not indicated
When required, refer to the analysis of pure reagents and GB/T 6682 in the provisions of the secondary water. The formulations and articles used in the tests were not indicated
Time, according to GB/T 601, GB/T 602 and GB/T 603 requirements.
4 sampling
4.1 Laboratory samples
According to the provisions of GB/T 6679 obtained.
4.2 samples
The laboratory samples were mixed evenly and about 40 g was fractionated by a quartile. The pellets were crushed and graded in a porcelain mortar.
The samples were passed through a 150 µm test sieve (according to the R40/3 series in GB/T 6003.1), placed in a weighing flask, dried at 105 ° C
To constant volume, remove into the dryer, cooling to room temperature, spare.
5 Preparation of sample solution (A)
5.1 Reagent
5.1.1 perchloric acid
excellent grade pure.
