Descrição

Descrição geral

Chromolith^® SemiPrep Si HPLC columns are ideally suited for direct scale-up from analytical to semiprep. This is because they offer faster sample throughput at a lower operating pressure compared to semi-prep columns packed with 5 μm particles.
Chromolith^® SemiPrep 10 mm i.d. columns combine high separation speed with excellent performance. This makes them the perfect alternative to particulate columns of 10 mm i.d. (and even 21.2 mm i.d.). They have the same bimodal porous silica rod structure as Chromolith^® analytical columns with an internal diameter of 4.6 mm. Their macropores are 2 μm in diameter and the mesopores are 13 nm. This combination dramatically reduces separation time while increasing efficiency.

The revolutionary, monolithic silica with its unique combination of macropores and mesopores enables:
—Rapid separations at very low column back-pressure
—High matrix tolerance, allowing time and cost savings with simplified workflows
—Cost-savings due to extended column lifetimes

The recommended Guard-columns are:
Chromolith^® SemiPrep Si 10-10 guard cartridges (3 pieces) [1.52035] with the Chromolith^® Guard Cartridge Holder 10 mm x 10 mm [1.52037]
