Short summary
Knowledge related to sulfur isotopic composition of carbonyl sulfide (OCS or COS), the most abundant atmospheric sulfur species, remains scarce. We present a new sampling system for collecting approx. 10 nmol of OCS from ambient air coupled with a purification system. The system presented herein is useful for application of sulfur isotopic compositions for investigation of OCS sources and sinks in the troposphere to elucidate its cycle and its contribution to background stratospheric sulfate.
