Impact of Sample Preparation on Dissolution Testing: Drug ...
dissolutiontech.comsample for determination of percent drug dissolved at a certain time point. This implies that following dissolution testing, filtration is a key sample preparation step to separate the dissolved drug from the undissolved dosage components. Filtration stops the dissolution process, removes undissolved drug, and allows sample analysis for amount ...
