Unisol Amide (agela HILIC)
Venusil XBP-Silica (Agela HILIC II)
Venusil XBP-NH2 (Agela HILIC III)
*Selectivity
XBP-silica is slightly acidic (pH=5.6); while Unisol Amide is slightly basic (pH=7.9), and XBP-NH2 is more basic (pH=9.2).
XBP-silica has stronger retention of basic compounds, while Unisol Amide and XBP-NH2 have better retention of acidic compounds.
Unisol Amide has a balanced retention power for neutral, acidic and basic compounds, and thus the highest versatility.
*Reproducibility and lifetime
Unisol Amide has the best reproducibility and lifetime because of a bonded and close-to-neutral protection layer.
