Short summary
Glaciers preserve organic compounds from atmospheric aerosols, which can serve as markers for emission sources. Most studies overlook the enantiomers of chiral compounds. We developed a two-dimensional liquid chromatography method to determine the chiral ratios of the monoterpene oxidation products cis-pinic acid and cis-pinonic acid in ice-core samples. Applied to samples from the Belukha Glacier (1870–1970 CE), the method revealed fluctuating chiral ratios for the analytes.
