Two types of experiments were conducted. The first involved heating the sample to 75 °C while keeping the sample isolated from the main vacuum chamber. When the sample temperature reached 75 °C, the sample compartment was opened to the main vacuum chamber, releasing a burst of evolved products into the chamber. A full mass spectrum was collected in the mass range of 12-250 m/z using a quadrupole mass spectrometer (Extrel) with electron impact ionization. The second type of experiment involved linearly heating the sample from -45 °C to 95 °C at a rate of 0.1 °C s -1 while the sample was exposed to the vacuum chamber. During heating, the mass spectrometer was set for single ion monitoring at m/z 44, identified during the first experimental approach. The temperature is held at 95 °C for about 10 min and then allowed to cool to room temperature.
