Claim Text:
1. An apparatus for analyzing a sealed container comprising: a) a waveform generator, which waveform generator is capable of producing a frequency swept electrical field; b) a first solenoid coil operably coupled to the waveform generator, which solenoid produces a magnetic field; c) a gradiometer comprising a top sample solenoid coil and a lower reference solenoid coil, wherein the top sample solenoid coil and the lower reference solenoid coil are counter-wound with respect to each other, wherein the gradiometer is positioned within the first coil, and wherein the container can be positioned within the top sample solenoid coil; d) a receiver operably coupled to the top sample solenoid coil, which receiver is capable of capturing a set of empirical data points reflecting a change in the magnetic field due to the contents of the container; and e) a computer operably coupled to the receiver and configured to empirically compare data from the set of empirical data points to known magnetic field empirical data from a known contents sealed container and thereby identify or authenticate the contents of the sealed container.
