Measurement of Gas- and Particle-phase Organic Species in Diesel Exhaust Using Vacuum Ultraviolet Single Photon Ionization Time-of-flight Mass Spectrometry
Organic compounds present in diesel exhaust were measured using vacuum ultraviolet single photon ionization time-of-flight mass spectrometry while heating the inlet line at high and low temperatures. Increases in signal intensities were observed when the inlet was heated at 623 K because of enhanced volatilization of the organic fraction emitted in the particle phase.
