Traceable Organic Certified Reference Materials for P-31 qNMR
The use of CRMs for the NMR quantification of phosphorylated organic compounds and metabolites offers several advantages as it is based on a signal comparison of the analyte with an internal or external reference standard.
NMR Analysis of Glycans
Nuclear magnetic resonance (NMR) spectroscopy measures the extent to which a glycan or other molecule distorts a magnetic field.
NMR Reference Standards
NMR reference standards ensure proper instrument performance. Review key operational parameters for these standards such as pw90, sensitivity, resolution and line shape.
NMR Deuterated Solvent Properties Reference Chart
Use this reference table to find the coupling values and chemical shifts of our NMR (deuterated) solvents. Melting and boiling points, molecular weight, density, and CAS number are also listed.
NMR Chemical Shifts of Impurities Charts
Reference or download our NMR shifts charts for the most common deuterated solvents. Proton NMR and carbon NMR tables aid chemists in separating signals of impurities that might originate from residual solvents or a reaction apparatus.
Biomolecular NMR: Isotope Labeling Methods for Protein Dynamics Studies
We presents an informational article concerning biomolecular NMR and the use of Isotope Labeling Methods for Protein Dynamics Studies.
Selective Protonation of Methyl Groups in Highly Deuterated Proteins
Presenting an article about the selective protonation of methyl groups in highly deuterated proteins. In which the structural NMR studies of small proteins, a maximum number of proton chemical shifts are usually assigned and NOEs connecting large numbers of sites
Certified Reference Materials for ¹⁹F Quantitative NMR Ensuring Traceability to “The International System of Units” (SI)
In certain cases, 1H qNMR reaches its limits, especially regarding the certification of complex and larger molecules. However, new fields of application often also bring along the presence of heteroatoms, namely 31P and 19F. We therefore introduced 3 CRMs for
