Fig. 2: Influence of extraction parameters on the detection of acetic acid.

A Acetic acid peak areas (n = 3), using two different extraction methods (SPME-trap and SPME-trap-enrichment) at 10 and 20 min durations. B Comparison of normalized acetic acid peak areas obtained via DTD or SPME-trap-enrichment. The acetic acid response for DTD and SPME have been normalized for each method to material 7 which shows the greatest acetic acid peak area for both techniques. C Silver, copper and lead coupons (from left to right) after the Oddy test. P means permanent use (no corrosion observed relative to control), T, temporary use (slight corrosion observed relative to control) and U, unsuitable use (significant corrosion observed relative to control).
