Dosage of hydrofluoric acid

Hydrofluoric acid (HF) , an aqueous solution of hydrogen fluoride, is an extremely corrosive and toxic mineral acid. It is widely used in the chemical industry for etching glass, manufacturing fluoropolymers, purifying metals, and formulating technical products. At very low doses, it can also be found as a contaminant in certain industrial processes or in matrices of natural or food origin.

The measurement of hydrofluoric acid is essential to guarantee product safety, prevent toxicological risks and ensure regulatory compliance of finished materials, food packaging, nutraceutical formulations or environmental residues.

Analytical methods used

The analysis of hydrofluoric acid is based on sensitive methods, adapted to its volatility and reactivity:

• Ion chromatography (IC): reference method for quantifying fluoride ions with high precision, even at trace levels.
• Acid-base or potentiometric titration: used for simple matrices or high concentration chemical formulations.
• Complementary methods: techniques such as ionoselective electrode (ISE) can also be used depending on the case.

These methods are carried out in specialized laboratories, equipped to safely handle samples containing HF, in accordance with current safety standards.

Affected matrices

The dosage of hydrofluoric acid is carried out in a wide range of industrial and environmental matrices:

• Materials and polymers: fluorinated resins, composites, technical coatings
• Food packaging: control of residues in barrier layers or technical inks
• Chemicals: descaling formulations, solvents, etching agents
• Food supplements or plant extracts: detection of traces in products based on fluoridated water or accumulating plants
• Water and effluents: control of industrial discharges or environmental pollution

The dosage is part of regulatory compliance, quality control, chemical risk assessment or product development processes.

Additional analyses available at YesWeLab

For a complete evaluation of risky formulations or matrices, YesWeLab offers several analyses complementary to hydrofluoric acid dosage:

• Analysis of overall or specific in food contact materials: in accordance with EC regulations No. 10/2011 and 1935/2004.
