METHOD OF CALIBRATING ELECTRON PARAMAGNETIC RESONANCE SPECTROMETRE AND CALIBRATION SAMPLE FOR REALISING SAID METHOD Russian patent published in 2010 - IPC G01N24/10 

FIELD: physics.

SUBSTANCE: calibration sample is put into a measuring resonator, which gives an anisotropic spectrum (EPR), made from a rutile monocrystal TiO₂ which contains Fe³⁺ ions in amount of 0.01-0.5 wt %. The calibration sample is turned in a magnetic field until appearance of an EPR anisotropic spectrum of Fe³⁺ ions whose lines are recorded and the EPR spectrometre is set using the said lines to maximum signal-to-noise ratio by moving the matching piston of the resonator and moving the bottom wall of the resonator in order to adjust the frequency of the resonator.

EFFECT: simple process of tuning and calibrating an electron paramagnetic resonance spectrometre.
