Opening claim text (preview).
What is claimed is: 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. 2. The apparatus of claim 1 , wherein the top sample solenoid coil is coupled to the receiver via an instrumentation amplifier. 3. The apparatus of claim 2 , wherein the instrumentation amplifier is operably coupled to an inverting gain amplifier, the inverting gain amplifier is operably coupled to an all-pass amplifier, and the all-pass amplifier is operably coupled to the lower reference solenoid coil. 4.

The method of claim 9 , wherein the statistical analysis comprises principal component analysis. 13. The method of claim 9 , wherein the test bottle of wine comprises an intact bottle of wine. 14. The method of claim 9 , wherein the test bottle of wine is a full sealed bottle of wine. 15. The method of claim 9 , wherein the change in the magnetic field comprises phase retardation or amplitude attenuation. 16. A method of authenticating a test sealed container, the method comprising: a) measuring a change in a magnetic field when applied to a known contents sealed container positioned within a gradiometer comprising a top sample solenoid coil and a lower reference solenoid coil thereby producing a first set of empirical data, wherein the known contents sealed container is positioned within the top sample 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 a first solenoid coil operably coupled to a waveform generator capable of producing a frequency swept electrical field, wherein the magnetic field is applied using the frequency swept electric field applied to the first solenoid coil, and wherein the frequency of the electric field ranges from about 500 Hz to about 30 MHz; b) applying a magnetic field to a test sealed container positioned within the gradiometer comprising the top sample solenoid coil and the lower reference solenoid coil, and measuring a change in the magnetic field, thereby producing a second set of empirical data, wherein the test sealed container is positioned within the top sample solenoid coil, wherein the magnetic field is applied using a frequency swept electric field applied to the first solenoid coil, and wherein the frequency of the electric field ranges from about 500 Hz to about 30 MHz; c) applying statistical analysis to the first and second set of empirical data to produce a first magnetic susceptibility profile and a second magnetic susceptibility profile; and d) comparing the first magnetic susceptibility profile from the known contents sealed container and the second magnetic susceptibility profile from the test sealed container, thereby determining if the test sealed container is the same as the known contents sealed container.
