REMINDER : NEO500 – CALENDAR AND QUEUE
Dear Users We hope that you have come to like the convenience of walking up to NEO500 without planning to reserve NMR time a priori. This is a decidedly efficient protocol in extracting maximum from the instrument as well. Nevertheless, ensuring the smooth running of this complex system that can always give you the data […]

SNAP POLL: GG500’s NEW BBFO iProbe – SOLICITING YOUR INPUT
Dear Users Just short of two months ago, I made an announcement about GG500 getting its own brand new fully automated BBFO probehead. Click on this link to that post, for quick reference. We ran into some technical challenges in integrating that probe with GG500, but they have been sorted out. The probe is ready […]

UPDATE ! GG500 — SYSTEM IS BACK TO THE USUAL INTERFACE – ROUTINE SPECTROSCOPY
Dear Users Sorry for the inconvenience and confusion caused from yesterday evening until a few moments ago, when the familiar ‘Green backdrop’ based Routine spectroscopy disappeared. In the process of troubleshooting the interface, I had to switch the system to ‘Automation Interface’, similar to what is present in the New NEO500 instrument. But, as I […]

REMINDER ! PLEASE RESERVE YOUR NMR TIME FOR GG500 AND 300 INSTRUMENTS !
Dear Users While we are very happy to see that you are all getting comfortable with the truely ‘walk-on’ nature of running NMR with our new NEO500 system, unfortunately, this process cannot yet be replicated on the other instruments. Until we get a fully automated setup with multiple sample handling on the other instruments, YOU […]

UPDATE ON NEO500 – SYSTEM WILL GET TO MAINTENANCE MODE IMMEDIATELY
Hello All The hardware parts reached earlier than exepcted, and the system is not shimming at all with the current configuration. It makes sense, therefore, to swap the hardware without any further delay and test it. As an upside, if everything goes well, the instrument will be released much earlier than expected. Please wait for […]

ALERT ! NEO500 – SYSTEM WILL BE DOWN BRIEFLY FROM 1.30 PM FOR HARDWARE WORK
Hello Users The remedial circuit boards that should resolve the intermittent Shim failure, will be installed and tested in the system starting from 2 PM and a bit of preparation is needed before that. Please do NOT queue any samples after 1 PM today. Any halted runs between 1 PM and the instrument down time […]

NEO500 : IMPORTANT CLARIFICATION ABOUT TUBE LENGTHS
Dear Users While you were trained on the new NEO500 system, you were told that it is OK to use the J-Young type tubes even with this fully automated system. This is definitely true, but certainly there is a caveat to that statement. Please look at the picture below. The ‘dotted line’ is roughly the […]
