10.1.3.1     Sample extraction
Low concentration (<200 μg/kg, for individual compounds):
    * purge and trap technique (Method 5035, Method 5030B)
Analysts should determine an appropriate concentration limit and ensure that results are based on sample concentrations that do not exceed the instrument range.

High concentration (≥200 μg/kg, for individual compounds):
    * methanol extraction followed by purge and trap technique (Method 5035 or 5030B).

10.1.3.2     Sample clean-up
Not applicable.

10.1.3.3     Sample analysis
