Filtration Methods for Dissolution Testing

 Request Information
Syringe filters remove undissolved active ingredients to get samples from exact time points.
Syringe filtration of dissolution testing samples removes undissolved active compounds, stopping the dissolution process and ensuring that each sample accurately represents the collection time point.
Spectroscopic analyses of pharmaceutical compounds in conjunction with dissolution testing plays a critical role in drug characterization and tablet quality control. Syringe filtering samples before spectroscopic analysis removes undissolved active compounds, stopping the dissolution process and ensuring that each sample provides an accurate representation of the collection time point. Undissolved particulates in dissolution samples, if not removed by the appropriate filter, continue to dissolve downstream, reaching downstream instrumentation such as HPLC. These particles are a major cause of variable test results and clogged HPLC columns that increase backpressure and shorten column lifetime.
