TD-NMR: minispec mq-series

TD-NMR uses a permanent magnetic field and radio frequency (RF) energy to look at NMR sensitive nuclei such as hydrogen and fluorine. In response, RF signals are generated by the sensitive nuclei and the signals are detected by the minispec. The amplitude and duration of these signals are related to the properties of the sample.
Unlike other spectroscopic techniques, TD-NMR is unaffected by sample color and surface properties. The minispec is perfectly suited to both QA/QC labs and R&D facilities because it is a nondestructive and non-invasive measurement that requires no sample preparation.

There are several published and well established methods for the minispec, including a number of international standard methods. In the food industry, Solid Fat Content (SFC) measurements are described in official methods by several organizations, including ISO, IUPAC and AOCS. In agriculture, oil and moisture in oilseeds and residues is determined by international standard methods. In the petrochemical industry, percent hydrogen in hydrocarbons like jet fuel and diesel are the subject of ASTM methods.
