Hi,
We have recently installed a new home source diffraction system
using MAR 345 dtb. It works much better than the rigaku because this
new device has automatic motor control system. However, we have a
lot of trouble to mount crystals. The magnet of MAR goniometer is
significantly weak so the pins do not stick on. The old pins we
used nicely in old rigaku are not working most of time. The new
pins from hampton research particularly designed for ALS
high-through put data collection are not easily working either. I
wonder whether anyone has similar experience and it could be fixed
by replacing with a stronger magnet base. Thanks for your
suggestions in advance.
Have you made sure that the electro-magnet for the goniometer is
switched on and working. You can switch the magnet on and off on the
control panel and a pin will not 'stick' without a green light here.
