The Orbit 100 C18 column (Dim°.: L.150 x Ø.4.6 mm), 5 µm, is a reversed phase column with a standard octadecylsilyl modification (other names: ODS, RP-18, C18). This modification, together with end capping, allows for pronounced hydrophobic interactions and can be used for all common analyses that rely on a C18 phase, whether in pharmaceutical analysis, environmental analysis, food analysis, or pesticide and residue analysis.

Performance characteristics and advantages
 - Nearly perfect spherical particles
 - High efficiency with low back pressure
 - High silica purity
 - Chemically and mechanically largely inert
 - Compatible with conventional HPLC systems

Further information
The Orbit series is based on almost perfectly spherical particles. This allows high efficiencies to be achieved with low back pressure. The Orbit columns have been developed specifically for routine analysis and offer high reproducibility. The service life can be increased by using suitable pre-column cartridges.
