W8288F Fluoride Ion Monitor

Short Description:

Fluoride Ion Monitor is an essential online analytical instrument designed for the continuous, real-time measurement of fluoride ion (F⁻) concentration in water. It plays a critical role in public health, industrial process control, and environmental compliance. Its most prominent application is the precise monitoring and dosing of fluoride in municipal drinking water systems, where optimal fluoridation is required for dental health protection. It is equally vital in industrial settings, such as semiconductor manufacturing, electroplating, and fertilizer production, where fluoride levels must be strictly controlled for process efficiency and to prevent equipment corrosion or environmental discharge violations.
The monitor's core is a fluoride ion-selective electrode (ISE), typically a solid-state sensor made from a lanthanum fluoride crystal. This membrane selectively interacts with fluoride ions, generating a potential difference proportional to their activity in the sample. An integrated measurement system automates the entire analytical cycle: it draws a sample, adds a Total Ionic Strength Adjustment Buffer (TISAB)—which is crucial for stabilizing pH, fixing ionic strength, and releasing fluoride ions bound by aluminum or iron complexes—and performs the potentiometric measurement and data calculation.
