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
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.
