Schematic illustration of experimental equipment for the permeability of the mask for the vaporized CPA. Figure 1 indicated the schematic illustration of experimental equipment for the permeability of the mask for the vaporized CPA. An aqueous solution of CPA (4 mg/2 mL) was vaporized in a chamber (1.1 L) and maintained at 60 °C. The CPA including air passed through three types of masks (100 cm2) using an air pump at a flow rate of 1.0 L/min for 1 hour. The air which passed through these masks was recovered in 10 mL of 50 % ethanol solution, and assayed by liquid chromatography time-of-flight mass spectrometry
