After cleaning the cell, the temperature of the cell (without a glass slide) was rapidly heated to 36 °C or 52 °C, and the vapors coming from the cell were monitored for approximately 30 min to determine the background signal from the cell. After the background signal was recorded, a glass slide containing the SOA was introduced into the cell already at 36 °C or 52 °C. The vapors coming from the cell and glass slide (held at 36 °C or 52 °C) were then monitored for 2 h. For each temperature, experiments were performed in triplicate.
