Metrohm USA METROSEP A SUPP 4/5 GUARD

Description

The Metrosep a Supp 4/5 Guard/4.0 reliably protects the Metrosep a Supp 4, 5 and 7 IC anion columns against contamination from the sample or the eluent. It contains the same separation material as the Metrosep a Supp 5, is also made of PEEK, and is screwed directly onto the respective separation column with nearly no dead volume ( in.On Column Guard System in.). The guard column prolongs the service life of the analytical column, with practically no influence on its chromatographic separating efficiency.
