Patent ID: 8710836

Claim:
An apparatus configured for detection of magnetic resonance in flowing sample material, comprising: a uniform sample conduit configured for containing a continuously flowing sample material, the uniform sample conduit comprising an excitation region and a detection region, each of which is located along a straight section of the uniform sample conduit, wherein the excitation region is operably coupled to the detection region and the excitation region is upstream of the detection region; a source of magnetic field configured to provide a substantially uniform magnetic field over a magnetic field region comprising the excitation region and the detection region; an excitation coil disposed within the magnetic field region and in the excitation region, the excitation coil configured for excitation of said continuously flowing sample material in the excitation region in order to generate magnetic resonance via excitation energy; a detection coil separate and distinct from the excitation coil, operably paired with the excitation coil disposed within the magnetic field region, and in the detection region, the detection coil configured for detection of magnetic resonance in flowing sample material in the detection region, wherein the excitation coil and the detection coil are on a micrometer scale from 100 micrometers to 530 micrometers; a transmitter operably coupled to the excitation coil and configured to transmit excitation energy to the excitation coil; and a receiver operably coupled to the detection coil and configured to continuously receive at least one magnetic resonance signal from the detection coil whereby a magnetic resonance signal from a flowing sample is continuously detectable within the uniform sample conduit.
