Abstract
The NMR analysis method for analysing a solid sample positioned in a sample-holder (21) includes generation of a plurality of high-pressure gaseous flows (2, 3, 4) from at least one first source (1) of a high-pressure gas; cooling of the gaseous flows (2, 3, 4) in at least one heat exchanger (12) from a coolant gas (15) originating from at least one second source (11) of gas; and rotation of the sample-holder (21) by a first cooled high-pressure gaseous flow (2) and cooling of the sample-holder by a second cooled high-pressure gaseous flow (3).
Claims20
NMR analysis method for analysing a solid sample positioned in a sample-holder which comprises the following steps:
- generating a plurality of high-pressure gaseous flows from at least one first source of a high-pressure gas;
- cooling the gaseous flows in at least one heat exchanger with circulation of a coolant gas originating from at least one second source of gas;
- rotating the sample-holder by a first cooled high-pressure gaseous flow and cooling the sample-holder by a second cooled high-pressure gaseous flow.
NMR analysis device, comprising:
- a sample-holder, suitable for receiving a solid sample to be analysed,
- at least one first source of a high-pressure gas for generating gaseous flows intended to rotate and cool the sample-holder,
- at least one heat exchanger,
- at least one second source of a coolant gas for cooling the high-pressure gaseous flows originating from the at least one first source in the at least one heat exchanger with circulation of coolant.
