Practical Dissolution Testing practical course
1 Day Course | GC Level 1

This one day course is an excellent introduction to the theory and principles of dissolution testing. This heavily regulated technique often appears simple to use, but the underlying theory and significance of the various apparatus and test methodologies is complex.

  • We limit numbers to 6 per course so that each delegate gets the opportunity to ask questions and fully participate in practical exercises
  • When delivered on-site we can design the course material to suit your specific training needs
  • Customisable written assessments are available if required

Ionic Interactions - Solubility

Ionic functional groups on analyte molecules are very different than hydrophobic or polar groups in that ionic group properties are a function of the charge state of the species. Therefore, the interactions of an ionic analyte with either a solvent or sorbent environment will similarly be influenced by the charge state.

From a solubility perspective, ionized groups tend to favor solubility in highly polar solvents. Therefore, bases at low pH (ionized) and acids at high pH (ionized) will be more soluble in highly aqueous solvents, including pure water, most buffers, and solutions containing water or buffers in combination with water-miscible organic solvents at relatively low concentration. (Acids)

Conversely, ionic groups in a neutral state tend to favor solubility in non-polar solvents. Therefore, bases at high pH (neutral) and acids at low pH (neutral) will be more soluble in more non-polar solvents such as acetonitrile, THF, ethyl acetate, chloroform, etc.(Bases)
