Nuclear magnetic resonance spectrometer (NMR)
minispec LF-series Bruker Optics

Since its first launch in the beginning of 2001, the minispec Live Mice Analyzer (LF50) has quickly gained market acceptance as a powerful, non-destructive and non-invasive tool for characterizing, screening and phenotyping mouse models in research laboratories. It has become the industrial standard for fat and lean measurement in live mice with installations in major pharmaceutical companies, diabetes and obesity research institutes and universities.

Nuclear Magnetic Resonance (NMR) methods are among the most useful non-destructive techniques of material analysis. Non-invasive examination of the body by means of NMR is extensive and has many useful applications, particularly with Magnetic Resonance Imaging (MRI) and Magnetic Resonance Spectroscopy (MRS). TD-NMR uses similar NMR technology, providing analysis of fat tissue, lean tissue and free fluid by the same physical selection rules that give rise to contrast in MRI. Tissue contrast is high between fat and muscle based on relative relaxation times.
