Do you have any knowledge of an instrument recently introduced that is capable of real-time online protein analysis? If it helps, some colleagues saw it here in Cambridge a week or so ago.

I think the event you are referring to was the bioprocess optimization seminar organized by Flownamics that took place in Cambridge, MA on February 28th. If that sounds about right, then the instrument in question is the Online Protein Analyzer from IDEX Health & Science. I have provided a link to more information about the instrument, including an application study, below.
