Toothpaste fluoride content tester (desktop nuclear magnetic resonance)
Fluoride is an important component of toothpaste. Adding a certain amount of fluoride to toothpaste can maintain the hardness of enamel and protect teeth. Fluoride ions can combine with minerals inside teeth to form fluorinated minerals, enhancing enamel hardness and thus protecting teeth. However, it should be noted that excessive fluoride may cause fluorosis and lead to dental fluorosis, which is actually detrimental to dental health. So the fluoride content in toothpaste must be effectively controlled and measured to ensure safety.
The traditional fluorine content testing method is titration, which is time-consuming, requires professional technicians, and requires the introduction of chemical acidic reagents.
Toothpaste fluoride content tester (desktop nuclear magnetic resonance)It is based on low field nuclear magnetic resonance method for fluoride content detection, which can effectively and quickly detect fluoride content. The fluorine content and the nuclear magnetic signal intensity of fluorine have a linear correspondence, and the fluorine content of the test sample can be quickly detected through simple calibration.
The fluoride content in toothpaste is usually between 1000 and 1500 ppm,Toothpaste fluoride content tester (desktop nuclear magnetic resonance)Fully capable of sensitivity and testing accuracy within this range.
