Reversed Phase (ODS)

ODS-AL is a non-endcapped high carbon load monomeric C18 phase. It is used only in those situations where residual sianol activity is beneficial to the separation.

It is not recommended for the analysis of amines or other compounds with basic functional groups present as peak tailing may occur.

• Possess residual silanols for mixed-mode separations
• Same high ligand density as other YMC ODS phases
• Unique selectivity for polar compounds

ODS-AL shows better separation for sakicylic acid and theopyhlline while
ODS-AQ couldn't work for them. Therefore ODS-AL is sometimes effective in separations of compounds that other ODS phases fail to resolve.
