YMC-Pack NH2 (Amino) Analytical Guard Columns

Normal-Phase Column Utilizing Amino Groups

YMC-Pack NH2 is a normal-phase separation column utilizing the polarity of primary amino groups bonded to silica.  It is a versatile stationary phase often used for the separation of sugars, but can also be used for separations utilizing weak anion-exchange.

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
