Nuclear Magnetic Resonance Fluorine Content Tester

Fluorinated materials are widely used in industry, and the fluorine content needs to be controlled in both industrial production processes and product quality in order to increase production and reduce toxic fluorine-containing gases. Low field nuclear magnetic resonance technology can quickly and accurately measure the fluoride content of solid, powder, and liquid samples.

The traditional methods for measuring fluoride content include titration, ion chromatography, etc. These methods are time-consuming, require professional technicians, and some even require the introduction of toxic chemical reagents.

Nuclear Magnetic Resonance Fluorine Content TesterCan be used for fluoride content testing of toothpaste, fluororubber, and other fluorine-containing substances (solid, powder, liquid are all acceptable).

Principle of Nuclear Magnetic Resonance Fluorine Content Testing:
The mass of fluorine contained in the sample is proportional to the corresponding nuclear magnetic resonance signal. Based on this principle, a sample with known fluorine content can be calibrated, and the fluorine content of the unknown sample can be obtained based on the calibration curve. This method has fast testing speed, no damage to the sample, and does not introduce other substances during the testing process. It can be used in scientific research and industrial fields.

Low field nuclear magnetic resonance method can quickly and effectively test fluoride content. Compared with traditional methods, low field nuclear magnetic resonance method has the following advantages:

1. Fast testing speed, usually completed within 1-3 minutes;
2. The testing process is non-destructive, and the samples can be reused;
3. The calibration process is simple and can be completed using 5-6 samples;
4. Low field nuclear magnetic resonance has high sensitivity and can detect samples with low fluoride content;
5. The instrument is compact and easy to install;
6. Easy to operate, no need for professional technicians, learn and use as needed;
7. Low field nuclear magnetic resonance is based on permanent magnet technology, with low instrument maintenance costs;
8. The nuclear magnetic tube can be reused without any other consumables;
9. Wide applicability, suitable for solids, powders, and liquids, with simple sample preparation;
