Description

Fluoride Standard CAS NO 16984-48-8 is a high-purity analytical reference material used for the precise calibration and validation of instruments in quantitative fluoride analysis. This standard is critical for ensuring measurement accuracy, regulatory compliance, and quality control in processes where fluoride concentration is a key parameter. It is an essential tool for analytical laboratories, environmental monitoring agencies, and quality assurance departments in the water treatment, pharmaceutical, and food & beverage industries.

Application

• Instrument Calibration: Primary standard for calibrating ion-selective electrodes (ISE), ion chromatographs (IC), and spectrophotometers used in fluoride detection.
• Environmental Analysis: Quantification of fluoride ions in drinking water, wastewater, and industrial effluent to ensure compliance with environmental safety standards.
• Pharmaceutical QC: Assay and impurity testing in fluoride-containing pharmaceutical products, such as dental care items and osteoporosis treatments.
• Food and Beverage Safety: Analysis of fluoride levels in products like tea, seafood, and public water supplies.
• Industrial Process Control: Monitoring fluoride concentrations in chemical manufacturing, metal surface treatment (pickling), and semiconductor etching processes.
• Clinical and Dental Research: Used as a reference in studies related to fluoride metabolism and the development of dental hygiene products.
• Method Validation: Serves as a traceable reference material for developing and validating new analytical methods (e.g., ASTM, ISO, USP methods).

Quality Control

Every batch of our Fluoride Standard is manufactured and certified in an ISO-compliant environment. The concentration is precisely determined against NIST-traceable primary standards using validated methods such as gravimetry and potentiometric titration. We provide a comprehensive Certificate of Analysis (COA) with each unit, detailing the exact assay value, uncertainty, measurement traceability, and stability data. Our quality system ensures compliance with relevant pharmacopeial (USP, EP) and ISO/IEC 17025 guidelines for reference materials.

Storage

Preserve in a tightly closed container, protected from light. Store at a controlled room temperature (15-25°C). Do not freeze. For long-term stability, it is recommended to store under recommended conditions and use before the expiration date stated on the label.
