Hi, So what's your secret - how did you pack an entire synchrotron into a little box?
OK, so I am being facetious a little. However, I cannot help asking myself why would I want to spend so much money on a system that is basically a (vertical) X-ray diffractometer in a box, with fixed distance, and sans the ability to collect data? I can only guess that the system costs in the range of $400K (am I right?) and for that money one could get a pretty nice actual X-ray diffraction set-up... Now, if this thing cost say ... $80K I may be interested, although most of our crystals are so small that this set-up will uniformly score them as 'no idea' because they don't even diffract at home on a 'real' X-ray source with a CCD. Artem P.S. the day I start routinely confusing protein and salt crystals is the day I stop working in the lab :) On Mon, Apr 18, 2011 at 3:00 AM, Marcus Winter <[email protected]>wrote: > > > > > > > Dear Chris, > > > > > > I’m prompted by your posting just to mention the Agilent Technologies > > PX Scanner ‘Crystal Challenge’ at: > > > > www.agilent.com/chem/crystalchallenge > > > > Thus, the only *really useful* assessment, or ‘score’, of objects > (putative > > crystals) – or crystallisation conditions, is by the actual observed > diffraction > > characteristics... and these preferably directly in situ, in the horizontal > > > crystallisation plate, as achieved in the PX Scanner. > > > > > > Many Thanks and Best Regards, > > > > Marcus Winter (Agilent Technologies) > > > > > > [image: > signature_crystalchall]<http://www.chem.agilent.com/en-US/Products/Instruments/X-raycrystallography/Pages/Crystalchallenge.aspx?cid=4710> > > > > > > > > *From:* CCP4 bulletin board [mailto:[email protected]] *On Behalf Of > *Chris > Ulens > *Sent:* 18 April 2011 08:24 > *To:* [email protected] > *Subject:* [ccp4bb] viewing and scoring crystallization drops on the iPad > > > > Our laboratory has been developing an application to view and score > crystallization drops on the iPad.
