RMN en el dominio del tiempo (TD-RMN)

RMN en el dominio del tiempo (TD-RMN)

The full name of time-domain nuclear magnetic resonance is Time domain NMR, or TD-NMR for short.

RMN en el dominio del tiempo (TD-RMN) is a NMR technique based on relaxation time detection. Time-domain NMR is generally tested and analyzed through T1 and T2 relaxation times. It is a characterization method, and the testing process is fast and non-destructive.

Time-domain NMR is widely used in scientific research and industrial quality control, with applications spanning food, agricultura, ciencia material, energía petrolera, nano-pharmaceuticals… como el contenido de grasa sólida (SFC) pruebas, seed oil content testing, fiber Oiling rate test, material aging and cross-linking degree, quantitative test of live animal body fat, etc..

Compared with the frequency-domain NMR analyzer, the time-domain NMR analyzer is generally a benchtop NMR based on permanent magnets, while the frequency-domain NMR is generally a superconducting magnet.

Time-domain NMR is to study the interaction between molecules, como la movilidad molecular, from the difference in relaxation time; frequency-domain NMR is to study the internal structure information of sample molecules from the frequency difference.

Application direction of time-domain NMR:

1. Relacionados con la calidad de los alimentos.: water molecular mobility, capacidad de retención de agua, unión de agua, hidratación;
2. Agricultural field: contenido de aceite de semilla, contenido de humedad de la semilla, seed soaking process, germinación de la semilla;
3. Food and agricultural product processing: investigación del proceso de secado, moisture migration, moisture distribution, low temperature freeze drying;
4. Material domain: envejecimiento del polímero, cross-linking, hardness research, etc.;
5. Industrial field: contenido de grasa sólida, tasa de engrase de fibra;
6. Geological energy domain: análisis de poros centrales, experimento de desplazamiento, congelar y descongelar, suelo congelado, concreto

The features of time-domain NMR:

1. Basado en tecnología de imanes permanentes, the maintenance cost is low;
2. Desktop NMR, the instrument is small and easy to install;
3. El instrumento es fácil de operar y puede realizar un funcionamiento automático.;
4. Time-domain nuclear magnetic resonance is generally designed as a single-use function, and there is no requirement for operators;
5. The permanent magnet material is stable and the instrument is very durable;
6. La aplicación de la RMN en el dominio del tiempo continúa expandiéndose, with powerful functions and wide application scenarios;
7. The time-domain NMR test process is non-destructive, rápido, verde y libre de contaminación;
