Sampling Method Of Boll Mill

Fast sample preparation for analysis of tablets

The ball mill sample preparation procedure is both quantitative and fast No powdering weighing and sonication steps are needed in the sample preparation The complete procedure takes 2 min (milling and extraction) and 5 min (centrifugation) respectively much less than the conventional method in which sample preparation takes approximately 45 90 min The samples are centrifuged in the mill
