KromaPhase is based on ultra pure spherical silica of high quality that provides high reproducibility and chemical stability using monofunctional silanes and total end-capping. KromaSil can be perfectly substituted for KromaPhase without changing the method. To ensure lot to lot reproducibility each lot is subject to specific controls. KromaPhase resolves the vast majority of analytical problems.
