Method and apparatus for sample monitoring

摘要

Method and apparatus for monitoring a sample having 'solid' and 'liquid' content using a magnetic field generator and subjecting the sample to a static magnetic field in the first direction to cause the magnetic vectors of nuclei to precess about the first direction. Thereafter, the bulk magnetic vector of the sample is reoriented so as to gain a component in a plane orthogonal to the first direction and monitoring the resultant FID. A pulse sequence is then carried out that causes the spins of the nuclei to rephase and produce echoes from which the solid and liquid components of the sample can be defined.
