GG500 : SYSTEM READY FOR USE – SAMPLE TUBE BREAKAGE FIXED
Based on what we observed, a sample tube broke while a user loaded the sample with spinner into the Carousel. This triggered an error condition of the Sample Robot. PLEASE PAY ATTENTION : With the Automation Hardware in place, we have reduced the physical human interaction with NMR machine to just a single step : […]

NEO500 USAGE PRACTICE – REMINDER
Like all instruments, NEO500 also has a walk-on usage policy where the software allows only a maximum of 60 minutes time during the day for a given sample. The software automatically queues longer experiments to so-called ‘Night Mode’ and runs them overnight. We are hearing that some users are stepping around this limitation by programming […]

UPDATE – NEO500 : ATMA issue resolved
Check the quality of your data if it was processed by the system before 3 pm today. If it is not satisfactory, please resubmit it. ATMA was non-functional until 2.45 pm. But the default tune/match might have been good for some of the samples. If that’s the case, the data collected should be OK. NMR […]

NEWS ! GG500 – WE ARE ADDING AN AUTOMATED SAMPLE CHANGER
Dear Users In the span of next week, you will see a ‘twin incarnation’ of the automatic sample handler that you see on NEO500 called SampleCase, appearing alongside the GG500 system and tested. We will give a headsup as to when this will happen with as much lead time as possible, but the installation process […]

UPDATE ! GG500 – READY FOR RESERVATION AND USE
Dear NMR community GG500 instrument is ready for use again. Please note the following : Topshim is working nominally. For deuterium based lock solvents, which means the majority of them, the shimming happens along the Z-axis only (known fact and a feature of the spectrometer hardware). You can start Topshim after loading the default starting […]
