YMC-Pack Polyamine II Analytical Guard Columns

Amino Column with Improved Durability

YMC-Pack Polyamine II is a silica-based, normal-phase stationary phase bonded with polyamine that is particularly useful for the separation of sugars.  The column lifetime in aqueous mobile phases is longer than conventional silica-based amino columns and is therefore applicable for the separation of oligosaccharides using high-aqueous mobile phases.  In addition, YMC-Pack Polyamine II can be used to separate ionic compounds with a combination of normal-phase and weak anion-exchange modes.

Guard Columns

Analytical Guard Columns: Features & Benefits

YMC’s Guard Columns for HPLC are available in 4.0mm and 5.0mm diameters and come in 10mm lengths.  These guard columns are available with a comprehensive stationary phase selection offered by YMC, ensuring compatibility between the guard column and the analytical column.  Unlike our guard cartridge columns, these guard columns do not require a holder, but do require a small jumper made from either stainless steel or PEEK tubing in order to connect them to the inlet of the analytical column.

(No holder required)
