Technical Information
Advantages of The selectivity is completely different from those of conventional columns such as ODS column due to its specific polar group in the stationary phase. Durability can be obtained by the high density bonding. Superior peak shapes of both acids and bases can be obtained because of neutral bonded phase and low residual silanol groups. Silica gel of high-purity is used as the support material, which minimizes effects of any remaining metal ions.

The selectivity is completely different from those of conventional columns such as ODS column, but the retention is close to conventional columns. is useful for the samples which are not separated by conventional columns. High durability can be obtained even if strong acid was used as mobile phase. is useful for the LC/MS analysis. Superior peak shapes of both acids and bases can be obtained because of neutral bonded phase and low residual silanol groups. Silica gel of high-purity is used as the support material, which minimizes effects of any remaining metal ions.
