High selectivity for aromatic compounds
pi-pi interactions between Phenyl groups and analytes play an important role when separating aromatic compounds. Inertsil Ph-3 is an ideal choice when compounds cannot be separated by hydrophobic interactions.
The figure below compares the seraration of aromatic compounds using Inertsil Ph-3 and Inertsil ODS-3. Inertsil Ph-3 achieves clean separation, whereas Inertsil ODS-3 cannot.
Taking advantage of the high selectivity, Inertsil Ph-3 is useful to examine the peaks obtained by other phase with different selectivity. The examples is shown below.
A sample of Soy bean extract was analysed by Inertsil Ph-3 and Inertsil ODS-3. The highlighted peak of Soy bean extract obtained by Inertsil ODS-3 (chromatogram in the middle ) is difficult to be determined if it indicates Carbendazim (peak 1). Whereas Carbendazim is not detected on the chromatogram by Inertsil Ph-3.
Comparing those chromatograms leads us to the conclusion that : there is no Carbedazim in this sample ; the peak in question of Inertsil ODS-3 is reflected by other components in the sample.
