From soft plastics to sharp spectra, diethyl phthalate (DEP) is well resolved on the QM 125 benchtop ¹H NMR. It plasticizes PVC and cellulose acetate and serves as a low-volatility solvent. Its symmetric phthalate core gives characteristic aromatic splitting.🧪

125 MHz ¹H NMR of Brilliant Blue shows the spectral signature of food dye. Its conjugated triarylmethane core gives distinct aromatic resonances, while sulfonated groups shape peak positions in aqueous solution. Used in sports drinks, candy, and blue raspberry products.🧪

125 MHz ¹H NMR of caffeine. Beyond its stimulant role, it provides key bitterness in beverages, making caffeine-free flavors hard to replicate. Its substituted xanthine core yields three N-methyl singlets and a characteristic aromatic proton.🧪

Either way, the limit-of-detection is about 20 nano-moles for a one-spin singlet and a single scan.
2) by turning the unit on its side so the path through the magnet is vertical, and then inserting a 1 mm OD glass NMR tube from above. The spectrum shown here was made the second way. The first way can be automated while the second way is simpler for walk-up applications.
There are two ways to handle samples as small as 5 uL: 1) using the standard tube but with the small-volume sample surrounded by an immiscible liquid, or
Our standard 1 mm ID polymer sample tube runs through the magnet and connects to the two front panel fluid fittings, as shown in the video. It has a total volume of 360 uL. In most applications the tube is filled from a syringe or by flow from the sample source.

Today I saw this enormous camphor tree at the Edison estate in Fort Myers, Florida. In his last years, Edison was obsessed with finding an economical source of latex that could be grown in the US. #NMRchat #ChemSky
Why does swapping a methyl group for a methoxy group cause such a big NMR shift?
At 125 MHz benchtop NMR, benzylic protons appear upfield, while the methoxy group resonates downfield. What’s driving this difference? Follow @qmagnetics.bsky.social for more spectra to come!🧪

When it comes to benchtop NMR, higher field doesn't have to mean higher cost. At 125 MHz, the QM-125 is the highest field of any non-super-conducting magnet at less than half the cost per MHz than other benchtop instruments.🧪

If Trump and his devils are not somehow stopped, America is about to see a Nazi ethnic cleansing of 10,000 adults and children in Springfield, Ohio.
Seems like a neat NMR spectrum of WD-40 of would be a good social media post for @qmagnetics.bsky.social We did a commercial acrylic cement that turned out to be mostly DCM.
Is 50:50 PLGA truly equal lactic and glycolic acid? Copolymer analysis relies on NMR integration. With 125 MHz field strength and high dispersion, the QM-125 enables benchtop quantitative PLGA analysis, directly compared to supplier COA data.
