Method of dissolution:
          
           1.   Measure a specified amount of standards in a sample bottle;
           2.   Add distilled water and dissolve it at 60℃ for 15-30minutes, stir the water gently until they dissolve homegeneously with the water;
           3.   Filtrate the solution with a 0.45 μm filter and a standard solution will be obtained.
 
Storage:
          
           1.   Store dry at room temperature in well sealed containers. Under these conditions, the product is stable for several years. 
           2.   When in a liquid state, keep it in a refrigerator at 4℃. If filtrated with a 0.45 μm filter and added 0.02 wt% sodium azide as an antiseptic, it can be preserved at 4℃ for 2 months.
