IC guard columns (precolumns)

This guard column reliably protects your IC anion column against contamination by the sample or eluent. It contains the same separating material as the Metrosep A Supp 5, is also made of PEEK and is attached directly onto the separating column with almost no dead volume («On Column Guard System»). The guard column increases the working life of the analytical column and has practically no influence on its chromatographic separating performance. The favorable price and simple handling are additional reasons for using the A Supp 4/5 Guard.
