Amino acids can be run on H-Class UPLCs. The most convienent (but fairly expensive) route is via waters' method. You can find details in waters' 2010-2011 catalogue or here:http://www.waters.com/waters/nav.htm?cid=514511.
I'm thankful for your kind reply.
I could analyze amino acid analysis using AccQ-Tag Ultra with H-class.
At this time, the AccQTag Ultra product is only qualified for use on the ACQUITY UPLC system which is a binary pump based system. The methods are not designed or supported to be run on the H-Class system which is a quaternary based pumping system. We have an active development project workng on modifying the methods for use on the H-Class system. We expect to offer full AAA support on H-Class, with the AccQTag Ultra product, sometime in early 2012.
