The small dead volume of the column guarantees an excellent peak shape. The Metrosep A PCC 1 HC/4.0 and the Metrosep A PCC 1 VHC/4.0, on the other hand, are high-capacity preconcentration columns for anions. They are used primarily where large sample volumes with very low anion concentrations must be preconcentrated. The high capacity prevents premature elution of the anions by the matrix itself (in most cases water). Reliable determinations can now be made using these high-capacity columns. All preconcentration columns are made of PEEK.
