Shining Light on Atmospheric Chemistry: A Breakthrough Method for Measuring Glyoxaland Methylglyoxal

Industry: Accurate measurement of glyoxal and methylglyoxal is crucial for understanding the
impact of volatile organic compounds (VOCs) on atmospheric chemistry, which affects air quality
and climate.

Challenge: Current methods for quantifying these compounds have limitations in sensitivity,
time resolution, and cost, hindering the development of spatially distributed databases for
comprehensive atmospheric monitoring.

Extraordinary Aspects of the Paper:The LIPGLOS method achieves impressive sensitivity
(3σ limits of detection of 11 pptv in 5 min for glyoxal and 243 pptv in 5 min for methylglyoxal)
and enables simultaneous measurement of both compounds using a single, non-wavelength-
tunable light source. This innovation promises the development of inexpensive, turnkey
instrumentation for long-term atmospheric monitoring, aiding in the validation of chemical
models and satellite observations.
