Fluoride Standard (0.5 ppm)

Features:

• NIST Traceable: Manufactured using high-purity raw materials and ultra-pure water to ensure traceability to NIST standards, supporting regulatory compliance and laboratory accreditation.
• Optimized for Water Testing: The 0.5 ppm concentration is ideal for establishing the lower end of a calibration curve for municipal drinking water, where fluoride levels are typically regulated around 0.7–1.2 ppm.
• High Composition Stability: Formulated to maintain ionic stability over its shelf life, preventing the concentration drift that can occur with poorly stabilized fluoride solutions.
• Interference-Free Matrix: Prepared in a high-purity aqueous matrix to ensure no background interference during Ion Chromatography runs or electrode potential measurements.

Safety & Regulatory Information:

WARNING! Chemical Hazard: While highly dilute, fluoride solutions should be handled with care.

• Personal Protection: Wear nitrile gloves, safety splash goggles, and a lab coat. Use in a well-ventilated laboratory setting.
• Storage: Store in a tightly closed polyethylene container at room temperature. Note: Never store fluoride standards in glass containers, as the fluoride ion can react with and etch silica, altering the standard's concentration.
• Handling Tip: When using an Ion Selective Electrode, always add TISAB (Total Ionic Strength Adjustment Buffer) to both your standards and your samples to ensure consistent ionic strength and accurate readings.
