The effect of photochemical reaction time on glyoxal and hydrogen peroxide at the aqueous surface is investigated using in situ time-of-flights Secondary ion mass spectrometry (ToF-SIMS) enabled by a system for analysis at the liquid vacuum interface (SALVI) microreactor. Carboxylic acids (i.e., glyoxylic acid, oxalic acid, malonic acid, tartaric acid) are observed in the initial reactions (i.e.,
