A "Small Shield" for a Big Job
The high purity base silica and thoroughly end capped bonded phases insure that CLIPEUS columns and cartridges will perform well in demanding situations where many other column brands fail.
Even polar compounds elute as sharp and symmetrical peaks permitting surprisingly short columns to be used for high speed analysis.
In addition to Silica,C8 and C18 phases, CLIPEUS columns are available with phenyl or cyano functionality.
