Abstract
An embodiment of the invention relates to a portable or handheld device for performing NMR analysis. The device comprises a console and a strip which can be placed into the console through a slot or other means. The strip comprises a sample holding place and a microcoil for generating an excitation magnetic field across a sample in the sample holding space. A permanent magnet is provided either by the console or the strip and generates a static magnetic field which, together with the excitation field, creates NMR within the sample. Other embodiments of the invention also encompass method of performing NMR analysis using the portable device and method of making such devices.
