Maurice - Your workhorse station for purity, identity and heterogeneity analysis
My molecule has complicated charge profiles that are difficult to resolve
My current method is not reproducible and error-prone
I have many samples and my schedule is tight
My sample is limited and they tend to aggregate at high concentration

Your workhorse station for purity, identity and heterogeneity analysis

Maurice innovates the conventional capillary electrophoresis technology to automate your protein profiling either by size or charge. Need cIEF and CE-SDS data for your mAbs, ADCs, vaccines or virus-like particles? Maurice does it all. Just pop in one of the preassembled cartridges, drop in your sample vials or a 96-well plate, and hit start. You'll complete your method development in a day and get high-resolution, reproducible data in minutes. Get compliant data with either Compass for iCE or Waters Empower software.

Purity, identity and heterogeneity

Still spending weeks or months on method development for your biologics? This new advanced CE platform lets you easily switch between cIEF and CE-SDS applications and develop platform methods within a day. In this short video, the people behind the gold-standard iCE technology highlight the key benefits of the new platform for CE analysts. Find out how Maurice makes CE easy with his streamlined workflow and delivers identity, purity and heterogeneity data on your biologics fast.
