Hydrogen content is one of the important indicators to evaluate the quality of aviation fuel, diesel and other products. The higher the hydrogen content, the better the gasoline combustion and the higher the quality. Quantitative analysis limited magnetic resonance method for the detection of hydrogen content in aviation fuel (pulse NMR) provides a testing scheme for industrial production, which conforms to the international standard test method ASTMD7171. This method has the advantages of fast detection, accurate results, easy operation and calibration, and the minimum sample preparation. Basic parameters for the quantitative analysis of hydrogen content in aviation fuel by limited magnetic resonance: 1. Magnet type: Permanent magnet; 2. Magnetic field strength: 0.5±0.08T; 3. Probe coil diameter: 18mm; Two calibration methods (quantitative analysis of hydrogen content in aviation fuel by limited nuclear magnetic resonance): 1. Direct purchase of pure hydrocarbons (e.g. dodecane) for calibration, international standard method recommends the use of pure hydrocarbons; 2. User-provided samples of known hydrogen content for calibration; Can be extended to: ASTMD3701 (aviation turbine fuel) ASTMD4808 (light and medium fraction oils, diesel and residual oils) Quantitative analysis of limited magnetic resonance method for the detection of hydrogen content in aviation fuel (pulse nuclear magnetic resonance) Advantages of quantitative analysis of hydrogen content in aviation fuel by limited magnetic resonance: 1. Fast test speed; 2. Simple instrument calibration; 3. Compared with traditional methods, the repeatability and reproducibility of nuclear magnetic resonance method are much better; 4. NMR method can be used for quality inspection and quality control in industrial production process, saving labor and significantly improving efficiency; 5. The instrument is easy to operate, and does not require dedicated technical personnel, and can be operated by untrained personnel; 6. Powerful functions for testing hydrogen content in fuel, in line with the test standard; 7. No requirements on the shape of the sample, the sample can be powder, granule, film or block; 8. NMR is a non-invasive and non-destructive test, the same sample can be measured repeatedly as needed; 9. The nuclear magnetic resonance signal is generated by all hydrogen nuclei within the entire sample volume, and the test result does not depend on the sample surface or sample color; 10. Can be used for 1H content testing in partial raw materials and chemical products; 11. Can be used for oil and water content testing in other chemical products; Low resolution nuclear magnetic resonance testing flow chart + magnetic analysis software
