NMR Crosslink Density Analyzer

Combined with the sample temperature control system, VTMR20-010V-T NMR analyzer can control the environmental temperature to research change in physical properties of samples over a wide range of temperatures and rates of change. It can be used for food, energy, organic materials and other areas of research.


1. Rapid cross-link density determination of rubbers and other polymers;

2. Relaxation analysis of T2*,T2 and T1;

3. Determination of glass transition temperature;

4. Quantitative analysis of water phase with varying -temperature.

NMR Application Indexes

1. Minimum detection limit: 10 mg of  water;

2. Test range of moisture: 0.88 % – 100 %;

3. The sample temperature range: 35 0C – 150 0C(standard)/ 35 0C – 2000C (advanced), with precision ± 0.3 0C;

4. The correlation coefficient of crosslink density between benchtop NMR method and swelling method > 0.99;

5. Repeatability: RSD < 2%, reliability: RSD < 10 %. RSD: relative standard deviation
