Have the Cake and
Eat It Too! 

Join us for a free, educational X-ray crystallography webinar! 

In this 1-hour webinar, Jens Lübben and Michael Ruf will talk about a new addition to Bruker’s APEX3 software for structure analysis: IDEAL - Invariom Derived Electron AnaLysis. IDEAL goes beyond the traditional Independent Atom Model (IAM) using IAM scattering factors and, in addition, models scattering contributions of bonds and lone pairs.

Now you can not only collect much better data to high resolution, but also appropriately describe additional electron density that cannot be modeled properly with the Independent Atom Model alone.

For the first time you do not have to choose to cut data in order to preserve a low structure reliability criteria R1, sacrificing additional information and overall structure quality. IDEAL lets you have the cake and eat it too!

Jens will introduce you to the theory of IDEAL, while Michael will focus on its practical application and implementation in APEX3.
