Looking to purchase and would like feedback from users

We have a couple of systems - standard - not H-class. Depends on what you want to use it for - if you want 4 bottles on top - quartenairy solvent system etc - you will need the H class, otherwise go for the standard one. But we have no problems with our systems and staff are happy with them. This response was provided to LabWrench by Nico van Loon

The two main differences, that I see, between the Classic and the H Class are Binary vs Quat and residence time. If you don't need Quat capability and need extremly fast methods go with the Classic. H Class has more flexibility at the expense of an additional 1-2 minutes per method. For both instruments, make sure you optimise your band width (called resolution for some reason) and your sampling rate. A sampling rate of 5 gives 2-3 times the sensitivity as a sampling rate of 20.
