Ion-Exchange DEAE Guard Column

Catalog Number	ACMA00046162
Description	Guard Column Assembly + Cartridge, Cartridge Only Guard columns are expendable small columns designed to remove anything that may interfere with the separation or shorten the lifetime of the primary column. A standard HPLC column (analytical or preparative) is hereby referred to as the primary because it is first in value and in importance for separation.
Application	DEAE Guard columns are expendable small columns designed to remove anything that may interfere with the separation or shorten the lifetime of the primary column.
End-Capped	Yes
Feature	Particles that may clog the primary column and necessitate a frit change, which can be cumbersome. Compounds, including ions, that may adsorb strongly on the packing material and cause baseline drift, spurious peaks, loss of resolution and change in selectivity Compounds that can form a precipitate upon contact with mobile phase or packing Compounds that may co-elute with analyte and interfere with its detection and quantitation.
