CM-100009 - HPLC Column EC 125/4 NUCLEODUR 300-5 C4 125 mm, ID: 4 mm

Wide pore RP phase for daily routine analysis. The medium density butyl modification is based on high purity NUCLEODUR silica gel and is often used for the separation of biomolecules. Butyl (C4) modifications have a lower retention for hydrophobic compounds compared to C18 (octadecyl silane, ODS) or C8 (octyl, MOS) modifications.
