Repeat experiment. Summary: 2 uL of liquid a-pinene was injected, followed by the injection of 100 ppb of N2O5 (source of nitrate radical) at a rate of 11.3 ppb / minute. After 60 minutes since the start of N2O5 injection, 0.4 uL of liquid limonene was injected, followed by the additional injection of 40 ppb of N2O5 (source of nitrate radical) at a rate of 11.3 ppb / minute.
