Methods for determining the identity of a substance are provided. A classification parameter set is defined to allow identification of substances that previously could not be identified or to allow identification of substances with a higher degree of confidence. The classification parameter set may include at least one of relative nuclear susceptibility (RNS) or an x-ray linear attenuation coefficient (LAC). RNS represents the density of hydrogen nuclei present in a substance relative to the density of hydrogen nuclei present in water. The extended classification parameter set may include T, T, and/or Tas well as at least one additional classification parameter comprising one of RNS or LAC. Values obtained for additional classification parameters as well as values obtained for T, T, and Tcan be compared to known classification parameter values to determine whether a particular substance is a known material.

A method and apparatus are provided for medium-field NMR scanning of liquids that is capable of discriminating benign liquids such as lotions, drinks, and pharmaceutical liquids from threat liquids such as components of home-made explosives.
