A triple quadrupole gas chromatograpy mass spectrometer (GC/MS/QQQ) was used to determine prebiotic molecules of interest in plasma and photochemical aerosols. Glycolic acid was further studied using isotopically doped gases. Plasma and photochemical aerosol analogs were shown to have nucleobases and a few amino acids. Each type of aerosol was also the source of glycolic acid, a precursor to glycine. Using 18O doped CO, it was determined that contamination was not a source of oxygen in the samples. Using different combinations of 13C doped gases in 1:1 combinations of CO and CH4, it was determined that under present reaction conditions 13C in high concentrations shuts down the photochemistry in the chamber.
