Conclusions:
The vapour pressure of Lyrame was investigated using the Transpiration method equivalent to OECD TG 104, gas saturation method, in a reliable non-GLP study. This is a dynamic method and has recently been updated for use of low volatile substances. A precisely known volume of air is sampled through a trap containing the sorbent Tenax TA. The adsorbed compound is desorbed and eluted onto a GC column where it is identified and quantified using a calibration curve. The mass of analyte per unit volume collected is used to calculate the vapour pressure. The vapour pressure of the Lyrame was found to be 0.00028 Pa at 24°C.

Executive summary:

The vapour pressure of Lyrame was investigated using the Transpiration method equivalent to OECD TG 104, gas saturation method. The vapour pressure of the substance was found to be 0.00028 Pa at 24°C.
