The objective of blend analysis is to determine whether the blend is uniformly mixed or not (very similar to CU, except BU is for powders and CU is for dosage units). What one needs is quick answers during blend analysis, so fast and simple methods are preferable. There is no need to develop a new HPLC method for blend analysis, since the CU method can easily be employed here. 

The process that explains how blend uniformity is performed is not the scope of this chapter. In summary, there are two ways to perform blend uniformity. Most common practice involves a thief that is utilized to sample
