CBIC Survey Closing

Thank you to everyone who participated in our CBIC Feedback Survey. We are closing the survey at midnight tonight (April 2nd). So, if you still haven't had a chance to provide your much appreciated feedback to us, please do so today at:

CBIC Instrument Updates

After several months of ongoing problems with nearly all of our X-ray diffraction instruments, we are pleased to note that these instruments ran smoothly throughout the month of March. The additional cold-streams we recently added have also been working well, improving the performance of our instruments -- especially the SCX-Mini. Moving forward, we are hopeful that the X-ray instruments will continue to run as well as they have been recently.

To help solve the ongoing sample changer problems, we have modified all the spinners for the A400c. This has indeed made the sample changer more reliable, by allowing a sensor in the magnet to more accurately detect the presence or absence of a sample. In the future, we plan to modify all of our spinners, except those used on the A600a. This instrument's sample changer has a different type of sensor, and so we ask that A600a patrons continue to use only the spinners designated for this instrument (marked "A600a only" on the spinner). An additional reminder to users of the A600a: Please be careful when loading your samples! We have had instances of samples being loaded into the location already occupied by a sample in the magnet -- in the best case, this mistake will halt the automation run, in the worst case this could break an NMR tube.

Finally, the A600a, along with many of our other instruments, was temporarily knocked offline by a brief power outage last Monday. All of the instruments are now back online. The power failure also took out two hard drives which have since been replaced. We have recovered most of the data and are working to recover the rest.

As per the planned trade in TA Instruments has removed the old MicroCal ITC 200. Patrons are encouraged to use the new NanoITC (located at the same table where the MicroCal used to be). The new instrument will provide comparable if not better data than the MicoCal. Those who did not attend the initial training session run by TA instruments upon the NanoITC's installation should get in touch with the CBIC staff before using the instrument.
