Dear Dr. Ross,
Thanks very much for your suggestion. I was thinking that there must be
people who have used both the systems. But, i see that its nearly
impossible to find.
Oxford system people have agreed to take our crystals by cryo-shipper
and try them out in their machine.

We had an Oxford Diffraction PX system, with the same goniometer and
detector as the Nova, for 3 years until last Fall when we upgraded to
the Nova. We also have 3 other Xcalibur instruments with the same
goniometer and control systems. All four diffractometers have
performed reliably with very little downtime, the oldest now being
nearly 6 years old, and with very little maintainance. The Nova itself
has worked well, and has stayed in alignment since it was installed 6
months ago. You can see a few more details at www.crystal.vt.edu.
I do not have experience of the micromax. Obtaining a valid comparison
between any two diffractometers is difficult. I can only suggest that
you do what the rest of us do, and that is take some of your typical
crystals and some of your poorer crystals around and try them out on
each of the instruments that you are considering.

Hi,
Our lab is planning to buy an X-ray machine for protein crystallography.
Which system would be best for home source, Oxford diffraction system
Xcalibur Nova or a MSC/Rigaku MicroMax-002.
sincerely,
sankar
