Abstract
An MRI-free non-destructive on-line system for detecting a presence of a material in a sample. The system includes a flow conduit encompassed by a tunable RF coil and having an input duct and an output duct; a flow of the sample through the flow conduit; a signal detector that detects frequency-dependent output signals as a function of a frequency variation of the RF tunable coil within a frequency range of an RF resonant frequency of a standard sample of the substance; and a processing unit.
Claims20
A non-destructive on-line method for detecting a material in a sample of a substance comprising:
- providing a flow conduit encompassed by the tunable radio frequency (RF) coil;
- providing a flow of the sample through the flow conduit;
- detecting frequency-dependent output signals as a function of a frequency variation of a radio frequency (RF) tunable coil have the sample disposed therein, the frequency variation is within a frequency range of an RF resonant frequency of a standard sample of the substance;
- determining an impedance frequency variation from the frequency-dependent output signals;
- determining an RF frequency variation of at least one characteristic of the substance from the impedance frequency variation;
- comparing the RF frequency variation of the at least characteristic of the substance with an RF frequency variation of a corresponding characteristic of a standard sample of the substance, wherein the comparison determines the material content of the sample.
