University of Oslo NMR Center - News

In the unlikely event case of a fast magnet quench in the NMR laboratories there have now been installed pressure-relief dampers in window openings.

They will open up in case of high over pressure from Helium and Nitrogen gas. If this happens you still have to get out immediately since the helium and nitrogen will displace all oxygen. Sensors (small black units) are installed in all rooms and will start to beep if the oxygen level is falling below life sustaining level. If you see one of them with a display indicting a non operational status (flat battery) please inform the senior engineer in the lab.

Please disregard this message if you are not using the automated "sj" and the "sj2" macros for running proton spectra on the BRUKER 200MHz spectrometer.
Two changes have been done to the "sj2" command:
ILDIGIT is now set at 2 which gives 3 digits after the decimal point in the integrals; 1.000 instead of 1.0000. (There is a bug in xwinnmr so no less then 3 digits are available)
PLDIGIT is now 3 which gives 3 digits after the decimal point for the ppm numbers of the peaks in the spectra; 1.000 instead of 1.00000.
If you have any questions regarding these macros just ask me.
Best regards
Søren

Morten Braendvang from Pronova Biopharma AS has discovered a quick way of importing an NMR spectrum from Xwinnmr into a MS Word document.
1. In edo, select curplot and curprin both as Clipboard after you have arranged everything concerning your plot nicely in xwinnmr.
2. type plot in xwinnmr's command line (the plot is not plotted - but sent to a clipboard).
3. open your word document and paste or Ctrl V and the spectrum is inside your word document.

Thanks to Morten :-)

Two NMR related master degree projects in Marine Biotechnology and Marine Chemistry are currently available. The students choosing these projects will do parts of their research work in industrial companies - one student in a company located in Ålesund on the west coast of Norway and the other student in a company in Bærum outside Oslo. Both companies are expanding and are looking for scientifically trained employees. Please contact frode.rise@kjemi.uio.no if you are interested.

The 10th National Norwegian NMR Meeting will be arranged in Oppdal January 16-18. Information can be found at:

An extensive search for the source of the error in the DPX300 instrument has been done. Many parts have been switched between the DPX200 and the DPX300 instrument in the search for the error, but it has been impossible to locate the faulty part. Due to economic restraints it is not possible to order service now. When the cryo probe service is performed on the AV600 and the AVII600 instruments in December 2007 the Bruker personnel will look at the DPX300 problem.

Our two 600 MHz instruments - AV600 (LC-NMR instrument) and AVII600 -(the triple alliance instrument dedicated for biomolecular research) are scheduled for Cryo probe service in the beginning of December. The instruments will be down one week.
