  • Methods and devices for polarised nmr samples
    Publication number: 20040049108
    Abstract: The present invention relates to devices and method for melting solid polarised sample while retaining a high level of polarisation. In an embodiment of the present invention a sample is polarised in a sample-retaining cup (9) in a strong magnetic field in a polarising means (3a, 3b, 3c) in a cryostat (2) and then melted inside the cryostat (2) by melting means such as a laser (8) connected by an optical fibre (4) to the interior of the cryostat.
