Development of Low Frequency Pulsed NQR/NMR Spectrometer

An FPGA based NQR spectrometer has been designed for detection of N nuclei. The digital circuits required for NQR spectrometer i.e Pulse Programmer, DDS, digital receiver have been built inside FPGA. Combining FPGA chip with analog components, NQR spectrometer has been developed. N from NaNO2 is observed using same spectrometer. By adding a permanent magnet of uniform field NMR signal of proton...

An Improved Cw Nmr Broad-line Spectrometer Forweak Signal Detection

In the article there is described a frequency-sweep nuclear magnetic resonance (NMR) spectrometer when a static magnetic field runs at a fixed value. The repetitive frequency-sweep of oscillator is realized by a variable frequency divider in the feedback loop of the second-order Phase Locked Loop. The largest advantage of this system for the CW NMR spectrometer is a good possibility of repetiti...

Next-generation Multidimensional NMR Spectrometer Based on Semiconductor Technology

We recently integrated all major functions – RF transmitter, RF receiver, and arbitrary pulse sequencer – of the conventionally bulky NMR spectrometer electronics into a fingertip-sized silicon chip and demonstrated various multidimensional NMR spectroscopy experiments with them, using various bioand organic molecules. We envision that the size and cost economy of such integrated spectrometer c...

Para-Hydrogen Induced Polarization at Time Domain NMR Spectrometer

Nuclear Magnetic Resonance (NMR) is a widely used spectroscopic method in a broad range of disciplines. Unfortunately NMR suffers from a low intrinsic sensitivity. The low sensitivity of NMR can be successfully improved by application of hyperpolarization technique called Para-Hydrogen Induced Polarization (PHIP) which was discovered in 1986 [1-3]. Till now, a substantial progress in the method...
