I do not have a lot of experiencein the field; we bought mini Dawn Treos from WYATT fro SEC-MALS and we have to receive now OPTILAB T-rEX (refractor index). I think that Wyatt altough is more expensive it is known as better quality and very good service (at least here in Israel). The SEC-MALS works OK for us. In January I am going to Santa Barbara for a course they are giving there.
Thanks for your help! I got similar feedback from others, which was my feeling from the beginnig, but as these equipments are quite expensive, I wanted to be sure about it.
Thanks once again,
we have been working for several years with a SEC-MALS (HPLC Waters-Wyatt MALS) and everybody is very happy with our set up here. We never used the MALVERN. You can look at the articles of C. Cambillau on lactophage baseplate characterization if you want technical details on our work.
My 2 cents, Renaud
