Method of dissolution:
          
           1.  Measure a specified amount of standards in a sample bottle;
           2.  Add distilled water and dissolve it at 90 for 1h, stir the water gently until they dissolve
                homogeneously with the water
           3.  The solution is then allowed to cool to room temperature and the volume adjusted to 50 ml. It can be
                preserved at 4 for 3 days.
 
 
Storage:
          
             Store dry at room temperature in well sealed containers. Under these conditions, the product is stable
             for several years
