Preferred term

ACES  

Definition

  • Principle of the Measurement: Cavity enhanced spectroscopy uses two mirrors to create an optical path of several tens of kilometers within a 50 cm measurement cell, making the instrument very sensitive to absorption by trace gases. Species Measured: Glyoxal (CHOCHO), nitrous acid (HONO), nitrogen dioxide (NO2) Time Response / Detection Limit: 30 pptv / 10 seconds for glyoxal and NO2 (en)
