Abstract: Processes and apparatuses are provided for contactless measuring or monitoring in-situ and in real time composition or other electromagnetic impedance correlated properties of liquid or gaseous substances or bulk materials. One or more apparatus may include a resonance type impedance sensor having at least two coils, at least one coil of the at least two coils being at least one excitation coil connectable to at least one alternating current source with frequency sweep, at least one other coil of the at least two coils being at least one sensing coil connectable to at least one data processing system. The one or more methods may include calculating changes in amplitude and resonant frequency induced by electromagnetic interaction between said sensor and object to determine impedance of said object under test; and matching said impedance with predetermined calibration data to determine said chemical or physical properties of said object under test.

Abstract: Processes and apparatuses are provided for contactless Nuclear magnetic resonance (“NMR”) spectrum acquiring and spectroscopic analysis and/or measuring or monitoring, in-line, in-situ and/or in real time, at least one composition or object under test of one or more solid, liquid, and/or gaseous substances and/or one or more bulk materials. One or more apparatus may include a resonance type impedance sensor having at least two coils, at least one coil of the at least two coils being at least one excitation coil, at least one other coil of the at least two coils being at least one sensing coil. The method(s) involve acquiring an NMR spectrum of an object under test while changing at least one of the frequency of an IR sensor and the intensity of the magnetic field applied to an object under test and/or sweeping intensity of the magnetic field applied to the object under test.
