YMC-Pack ODS-AL

YMC-Pack ODS-AL uses not only hydrophobic interaction but also secondary interactions with reactive residual silanol groups to affect separation. This results in a different selectivity from conventional ODS columns. When ionic interactions are involved, it is preferable to use a buffer in the mobile phase to achieve reproducibility of chromatograms.

Features:

• possesses residual silanols for mixed-mode separations
• same high ligand density as other YMC ODS phases
• unique selectivity for polar compounds

YMC-Pack ODS-AL is stable towards hydrolysis between pH 2-7,5. Remove acid and buffer salts before storage. Store the column in methanol / water = 70/30.
