Obtaining the calibration signal during analytical works on NMR-spectrometer JNM-3H-60, VN-2

Abstract

The high sensitivity of the NMR spectrometer JNM-3H, BH-2 (Japan electron optics laboratory Co. Ltd.) allows its use for express quantitative analysis of solids. One of the significant difficulties in this case is related to the recording of the calibration signal, which allows taking into account the analysis errors that arise as a result of uncontrolled changes in the hardware parameters of the spectrometer. First of all, these include changes in the goodness of the sensor circuit due to the variability of the electrical properties of the substance under study and changes in the gain of the receiver.
