Short summary
Formaldehyde is the most abundant aldehyde in the atmosphere and plays an important role in photochemistry. Broadband cavity-enhanced absorption spectroscopy uses a high finesse cavity to obtain effective path lengths of kilometers. We use a diode-pumped plasma lamp and custom cavity mirrors to extend this technique further into the ultraviolet spectral region, and we achieve detection limits of hundreds of parts per trillion in 1 min for formaldehyde and nitrogen dioxide.
