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,
