My colleague Tyler Ozvat recently posted this NMR spectrum of tartrazine (FD&C yellow #5). The hydrazone NH proton has a chemical shift of 17.8! Don't the textbooks say the most deshielded protons are carboxyl and aldehyde? #NMR #NMRchat #benchtopNMR #chemistry

The tools we use are one of my favorite things about making #QMagnetics #benchtopNMR spectrometers. Yesterday we received new Borite lathe tools with TT-321 carbide inserts. The inserts are supposed to have a 1/64” tip radius. That’s important, so we checked them on an optical comparator. #NMR #scientificInstruments #chemistry #machinist

Here's a PTS-160 frequency synthesizer from my test equipment collection. PTS synths were supplied with #Varian #NMR spectrometers and are still commonly used in NMR labs. This one has seen heavy use in the Q Magnetics #QMagnetics R&D lab where we developed the world's highest field benchtop NMR spectrometer. The ancient HP-5328A counter on top has not been checked against a standard for >20 years. #NMRchat #benchtopNMR #electronics #chemistry

I’m the kind of #physics person who likes to build #ScientificInstruments, lately #benchtopNMR #spectrometers for #chemistry. I need lots of #tools to do my thing. This is my #Hardinge HLV-H #lathe, just after I finished a renovation in 2017. It was made in 1968 in Elmira, New York. In that era in the US, there were two competing high-precision “tool room” lathes, this one and the Monarch 10EE.

I’m the kind of #physics person who likes to make #scientificinstruments, recently #benchtopNMR spectrometers. I need a lot of tools for what I do, some electronic, some chemical, and some mechanical. Here’s my Starrett bench micrometer. Look closely and you can see it’s giving the right answer for a 40 mm gauge block. #chemistry #NMR

@heydebigale I’m recently retired from CU #physics and now chief scientist at http://www.qmagnetics.com a new #benchtopNMR company. Hoping to see a lot more #chemistry #NMR and #spectroscopy here.
