HPLC Column Raptor C18, 90Å, 2.7 µm, 50 x 2.1 mm

Restek chemists were the first to combine the speed of surface porous particles (also known as SPP or "core-shell" particles) with the resolution of highly selective USLC technology. With this new generation of chromatographic columns, you can achieve better peak separations and shorter analysis times with existing HPLC and UHPLC instruments.

When you need a general-purpose LC column, don't just pick any C18. Opt for the speed, efficiency, and durable ruggedness of the Raptor C18. This traditional endcapped C18 phase offers the highest hydrophobic retention of any Raptor phase and is compatible with a wide range of mobile phases from moderately acidic to neutral (pH 2-8). Whether for food safety, environmental or bioanalytical analysis, this phase provides consistently excellent data quality in less time for a variety of reversed-phase applications, matrices and compound classes. To reduce costs and increase profitability, columns must last longer, data must be reproducible, and existing HPLC and UHPLC instruments must run faster. Achieve your goal with the only general-purpose C18 column that gives you accelerated selectivity.

Switch to a C18 column:

When you need a general-purpose column for reversed-phase chromatography.
When you need to increase the retention of hydrophobic compounds.

Note: We strongly recommend that you only order a semi-preparative or preparative column once you have evaluated the desired separation on an equivalent column on an analytical scale.
Because we cannot reuse a column or the silica within it once it leaves our facility, we cannot accept returns of large columns.
