Table 2 Summary of pad control experiments. Each condition describes the experimental treatment of cotton and viscose/polyester pads, along with the volumes of water used and number of replicates. Pristine pads were used as received, pretreated pads were heated to 150 °C for 20 minutes.

Condition | Description | Cotton pads | Viscose/polyester pads |
|---|---|---|---|
1 | Pads “pristine” (extractions at 25 °C) | 0, 100, 200, 300, 500 \(\mu\)L water (4 replicates each) | – |
2 | Pads “pristine” (extractions at 60 °C) | 0, 100, 150, 200, 300, 500 \(\mu\)L water (5 replicates each) | 0, 100, 150, 200, 300, 500 \(\mu\)L water (5 replicates each) |
3 | Pretreated pads at 150 °C (extractions at 60 °C) | 200 \(\mu\)L water (5 replicates each) | 200 \(\mu\)L water (5 replicates each) |
