This document describes the design and usage of the Guard Column, which is intended to be used in conjunction with analytical columns for protection against particulate matter and other damaging material in the eluent or sample. It is recommended to filter the eluents and samples before use. The same flow rate, pressure, and solvent restrictions as detailed in the Users Guide apply to Guard Columns.
This document describes the purpose of a Guard Column, which is designed to be used in conjunction with relevant analytical columns. It should be connected immediately prior to the first analytical column to provide protection against blockage by particulate matter and other damaging material in the eluent or sample. It is recommended that eluents and samples are filtered (0.5 um) prior to use, and the same flow rate, pressure, and solvent restrictions detailed in the Users Guide apply.
The document also provides specific installation warnings regarding the connection of the guard column to the system. To avoid loosening end fittings and causing column leakage, users must follow the indicated wrench usage instructions rather than using a wrench on the flat end fitting.
It provides protection against blockage by particulate matter and other damaging material in the eluent or sample.
It is recommended that eluents and samples are filtered with a 0.5 um filter prior to use.
