Quantitative Determination of Acetaminophen by q-NMR. Note: If we do not select manually the peaks before the DOSY processing, then Mnova applies an automatic peak peaking over the full spectrum. Instead, the ERETIC method (Electronic Reference To access In-vivo Concentrations), in which a reference signal was generated by an electronic device, was utilized, which showed a difference of up to 15% with the internal reference method.

The q-NMR experiments were repeated without utilizing the internal standard. More than half of the data showed percent standard deviation values under 1%, indicating that the data had high precision. You can also choose Auto Scale form the Stack menu. Next, go to the top menu and choose Stack and choose your desired option.

concentration for both sets of concentrations and three different sets of protons showed linear relationship with regression values ranging from 0.9979 to 0.9998. Once all of the same spectra are drawn you can superimpose or stack the spectra by first left clicking on one of the small navigation windows on the very left then holding shift and click on the other spectra to stack.

The peak integration data were analyzed by TopSpin software of the NMR spectrophotometer as well as by MestReNova software from Mestrelab Research. The peak area of three sets of protons in acetaminophen вЂ“ methyl group peak and two sets of aromatic ring peaks вЂ“ were quantified with respect to the methyl group peak area of the internal standard, ethanol. Two sets of concentrations of acetaminophen in deuterated dimethyl sulfoxide вЂ“ ranging from 10 mM to 100 mM and 1 mM to 10 mM вЂ“ were analyzed using ethanol as an internal standard in septuplicate to show the robustness of the method. In this study, quantitative analysis of acetaminophen (active ingredient of Tylenol) was accomplished by q-NMR technique using a Bruker 300 MHz NMR instrument. uncertainty when faced with integrating an NMR instrument into your students.

page 25 D.Quantitative 1H-NMR technique (q-NMR) provides a rapid, selective, and accurate method for quantification of wide variety of organic compounds using minimal solvent, thus making it an environment friendly technique.

Ideally we'd get some newish (not 30 years old) spectra in an interface where students could, for instance, integrate NMR peaks and zoom into multiplets, automatically get a list of wavenumbers in IR spectra, maybe even deconvolute mass spectra.
