Dear all,

It was great to see you in London last week. As I mentioned on Friday, I would like your feedback before going into a full scale cross-network CD comparability study. I have prepared a short survey (link below) which covers the feedback for the current pilot study and also includes a participation form for the full scale project.

Let me know if there are any problems with the survey or if I missed something.

Thanks again to all the participants of the current study.

Best wishes,

Nikola

There was an error with the survey that was preventing anyone from submitting the answers - it should be fixed now.

My apologies, if anyone has lost their answers.

Thanks for your efforts on this study.

You were correct in your comment on pathlength accuracy in London. On 1 mm pathlength the error is 1%.  I was recalling my experience when I built a continuous flow instrument using a 0.1 mm pathlength cell where the error is 5%. Since the cross section area was needed in calculating flow velocity, this was compounded to 10% !  A good reason to stick with 1 mm fixed cells in your studies.

Dear all,

Just a quick reminder, the participation fom is still open and we haven't received as many sign ups as could be hoped for a truly comprehensive study across the network.

Thanks,

Nikola

Hi, is your comparability study referring to Biosimilar Comparability Studies?
