Short summary

In this paper, we present a compact, affordable and robust instrument for in situ measurements of different trace gases: NO_x, IO, CHOCHO and O₃ with very low detection limits. The device weighs 15 kg and has a total electrical power consumption of < 300 W. Its very low detection limits and its design make it suitable for field applications to address different questions such as how to better constrain the oxidative capacity of the atmosphere and study the chemistry of highly reactive species.
