Chromolith® HighResolution columns allows you to enjoy greater flexibility of flow rates, faster analyses, and a longer column lifetime. Each Chromolith® column consists of a single rod of high-purity polymeric silica gel with a bimodal pore structure of macro and mesopores.
The macropores reduce column back pressure, allowing significantly faster flow rates. The mesopores form a fine porous structure, which creates a very large active surface area for high-efficiency separations. For even greater efficiency, multiple Chromolith® columns can be coupled to achieve a higher theoretical plate count with still very low back pressure
