5. Summary
The box opposite summarizes the procedure and recommendations for sampling with the new sampling device.
– Conditioning and evacuation of sample vials using a canister-specific system (e.g. "Cleaner" type). A diaphragm vacuum pump can also be used with acceptable performance.
– Packaged vials can be stored for up to five days. Before sampling, the pressure in the vial must be checked with a manometer.
– Instant sampling is performed by opening the vacuum valve. Additional vials are required for transport and storage.
– SPME pre-concentration is preferably carried out in the laboratory, for better control of conditions and to reduce the number of fibers. Samples should be stored for as short a time as possible (24-48 h)...
