| def: A sample that has been prepared for chemical analysis by NMR. NMR samples are usually liquid solutions contained in glass tubes. NMR solution sample volume ranges from 50ul to 5ml depending on the NMR probe. Sample concentrations of solute for 1H NMR are usually in the range of 100ug to 5g, with 10 to 50mg being typical. NMR is not a chemical trace analysis technique. The NMR signal of solids and gases can be recorded but to measure solid-state NMR additional specialized hardware is required.
