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.rKromaSil can be perfectly substituted for KromaPhase without changing the method. To ensure lot to lot reproducibility each lot is subject to specific controls.rKromaPhase resolves the vast majority of analytical problems.rrKromaPhase specifications SIL: r- USP Code: L3r- Particle sizes: 3.5, 5, 10 µm r- Pore size: 100 Å r- Surface Area: 300 m2/g r- pH range: 1 to 8 r- Pore volume: 0.8 mL/g r- Particle size distribution (D10/D90) < 1.6
