Answer:It is a 2 mm × 50 mm microbore guard column.
Answer:It is designed to protect compatible Dionex IonPac CS12A cation-exchange analytical columns.
Answer:The guard column uses 8 µm cation-exchange resin.
Dionex™ IonPac™ CG12A Guard Column is used to protect the matching CS12A microbore analytical column during cation chromatography. This 2 mm × 50 mm guard format contains the same 8 µm cation-exchange chemistry used in the CS12A family, preserving chromatographic selectivity while trapping strongly retained contaminants and matrix material before they enter the main analytical bed. The column is suited to acidic-eluent separations of lithium, sodium, ammonium, potassium, magnesium, and calcium in water, process samples, soil extracts, acid digests, and other matrices. Its microbore format conserves eluent and supports the same analytical system geometry as the 2 mm CS12A column. The guard column is rated to 4000 psi and is compatible with acidic eluents and acetonitrile, while alcohols should be avoided. Routine replacement can help maintain analytical-column efficiency, retention stability, and service life.
