Columns for Organic Solvents
How to Choose Optimum Stationary Phase
The PSS column concept is to minimize interactions between polymer and stationary phases by providing stationary phases of different polarities.
In general, the sample is the determinant factor: the polarity of the sample defines the polarity of the solvent and therefore also that of the stationary phase. To ensure interaction free chromatography the stationary phase needs to be selected carefully.
The PSS Magic Triangle provides a quick visual aid for the selection of columns, where the three sides represent sample, mobile phase, stationary phase.
How to Use the PSS Magic Triangle
By reference of the polarity of sample and mobile phase; the peak of the Magic Triangle guides you to the proper stationary phase. This concept is also applicable for aqueous GPC/SEC.
