Ultra Compact NMR

Unilateral NMR device for University of California – Davis, Food Science Department.  Fruit samples can be set on top of the coil for T2 determination.  Its sensitive region is about 8mm long, axially, centered 17mm from the end of the magnet with a working field strength of 0.13T (or Larmor frequency of 5.5 MHz for protons).

One of its potential uses is to non-invasively measure sweetness of watermelons because T2 is correlated with sweetness.
