General description

A Chromolith® CapRod capillary column combines the speed of monolithic silica technology with the sensitivity of nano-LC. This enables superior productivity for high throughput, highly sensitive proteomics-LC applications.
Compared to particulate capillary columns, Chromolith® CapRod capillaries demonstrate better performance with optimal resolution (narrow peak widths), increased productivity (higher sample throughput), and extended column lifetime. Furthermore, column length is less limited than with any other type of column. The capillaries can even be slightly bent to fit any LC configuration or instrument.
Chromolith® CapRod columns are designed to work with various nano or capillary-LC systems. This provides the highest efficiency and performance when coupled to mass spectrometers, both on-line (ESI, nanospray) and off-line (MALDI).

Why choose Chromolith® CapRod capillary columns?
—Higher flow rates than particle-packed capillary columns
—Columns at low pressure
—Long column lifetime
—Robust and easy handling
—Flow rates from 0.1–200 μL/min ensure ideal compatibility with LC/MS systems, with both ESI and APCI interfaces

Chromolith® CapRod RP-18 endcapped monolithic Trapping Column is a capillary trap that is used to concentrate samples before transfering them to the analytical Chromolith® CapRod column. The typical flow rate for this 50-0.2 trap capillary column ranges from 10 μL/min to 50 μL/min.
