Columna HPLC NUCLEODUR® 300-5 C4 ec, 250 mm, 4 mm, 1 Pieza(s)

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.

Similar phases:
Jupiter^® C₄; ACE^® C₄.

For protection of your main HPLC column from contamination, it is recommended to use guard columns. These short columns are placed into a guard column holder. The guard column holder in combination with a guard column inside is installed between the injector and the HPLC column. This installation prevents chemical impurities to reach the main column. Because a contamination could form an irreversible bond with the column packing material (stationary phase) and this can result in shorter column life. If you want to prolong the lifetime of your main column, then these short columns can help you.
