TSKgel® Aminopak is a specialty column for the analysis of free amino acids by ion exchange. The column is packed with polystyrene-based particles that have been functionalized with sulfonic acid groups. Detection is performed by post-column reaction with ninhydrin or o-phthalaldehyde. The primary application of TSKgel Aminopak is for the analysis of amino acids in food. No guard column products are offered to protect TSKgel Aminopak columns. It is recommended to use a frit or screen fiter (<2 micron porosity) between the injector and the column. Samples and mobile phases are best filtered and degassed through a 0.45 micron membrane filter.
