INTRODUCTION
The SPME-Adapter has been developed to simplify spot sampling of VOCs in air. This interface combines vacuum air sampling with SPME pre-concentration. The vacuum flasks used are similar to canisters, but are less expensive and easier to set up. Air is removed by opening a vacuum valve. The SPME fiber is then introduced into the flask to pre-concentrate the VOCs. Detection limits reach μg · m –3 , with a reproducibility of 12%.
To simplify grab VOCs sampling in air, the SPME-Adapter was developed. This interface allows combining vacuum sampling in an evacuated vial with SPME pre-concentration. Vials are similar to canisters but cheaper and easier to implement. The vacuum valve of the SPME-Adapter is simply open to let in the air. Then the fiber is introduced to perform in-vial extraction. A 30 min sampling time allows detecting and quantifying μg · m –3 levels with 12 % reproducibility.
