Determination of saturated vapor pressure

Saturated vapor pressure is the pressure at which a liquid is in thermodynamic equilibrium with its vapor phase, at constant temperature. This parameter is essential for assessing the volatility, stability, or environmental behavior of many substances, particularly in the context of REACH, CLP, or biocide regulatory analyses.

Its dosage is recommended for:

• Characterize organic solvents and volatile compounds
• Assess the risks of evaporation or dispersion
• Determine the content of volatile substances in formulations or extracts

Available analytical methods

YesWeLab offers two complementary approaches depending on your matrices and objectives:

• Manometric method: direct measurement of vapor pressure at different temperatures
• Thermogravimetry (TGA/ATG): measurement of mass loss under controlled atmosphere, often coupled with chromatography to identify volatile fractions

The methods are adapted to European regulatory requirements and can be developed to meet your specific specifications.

Affected matrices

Saturated vapor pressure analysis is applicable to different types of samples:

• Pure solvents or mixtures
• Volatile ingredients in cosmetic, phytosanitary or technical formulations
• Natural extracts (plants, essential oils)
• Material processing products
• Substances subject to REACH authorization or biocides

Industrial applications

This analysis is aimed in particular at professionals in the following sectors:

• Environment: assessment of the potential for atmospheric dissemination
• Fine and regulatory chemistry: REACH characterization, SDS
• Cosmetics & perfumery: control of volatile ingredients
• Agrochemistry: characterization of volatile active ingredients in biopesticides

Further analyses recommended

• Thermogravimetric Analysis (TGA) – for thermal stability and mass losses
• Analysis of residual solvents – for the targeted determination of volatile substances
