LCS Laboratory Inc. offers unique vapour pressure testing of compounds, providing critical data for regulatory documents like SDS preparation. Using the OECD 104 method and a high-sensitivity setup, we measure vapour pressures from 0.1 to 100 Pa at room temperature, delivering reliable results with a sensitivity of 0.1 Pa.
Vapour Pressure Testing Process
Our testing method uses a saturated vapour technique, where air is saturated with the vapour of your product until equilibrium is reached. The vapour is then condensed in a cold trap or adsorbed onto a medium, followed by analysis by HPLC-UV or GC FID. This allows us to calculate and report the vapour pressure with high accuracy.
Requirements for Vapour Pressure Testing
To ensure accurate results, the sample must meet specific criteria:
- Pure chemicals only with a known molecular formula and molecular weight
- Stability in contact with air
- Detectable by GC or HPLC methods
- Testing conducted at 25°C
- Results based on the average of three measurements for reliability
