A simple setup for dynamic air sampling using a solid-phase microextraction (SPME) device
designed for use in the field was evaluated for organophosphate triester vapour under both
equilibrium and non-equilibrium conditions. The effects of varying the applied airflows in the
sampling device were evaluated in order to optimise the system with respect to the Reynolds
number and magnitude of the boundary layer that developed near the surface. Further, the
storage stability of the analytes was studied for both capped and uncapped 100-
m PDMS fibres.
Organophosphate triesters are utilized on large scales as flame-retardants and/or plasticizers, for
instance in upholstered furniture. In indoor working environments these compounds have become
common components in the surrounding air. Measurements were performed in a recently
furnished working environment and the concentration of tris(2-choropropyl) phosphate was
found to be 7
