revisions point out a bulk density noticeably decreased than anticipated for an Earth-like rocky interior,
This doc presents an outline of varied dissolution testing approaches. It begins with definitions of dissolution and an evidence of the need for dissolution testing. It then describes the key classification of approaches as official and unofficial. The official techniques discussed intimately tend to be the basket, paddle, reciprocating cylinder, movement by cell, paddle in excess of disk, and rotating cylinder apparatuses.
