Please register to view a playback recording of this webinar featuring Picarro Research Fellow, Chris Rella, PhD and Application Specialist, Caleb Arata. They discuss how carbon isotopes measurements are made via Cavity Ring-Down Spectroscopy (CRDS) and how careful calibration can improve the stability of measurements for demanding atmospheric applications. If you want to learn more about how to optimize your calibration protocol and field set up for measuring δ¹³C in ambient atmospheric CO₂ and CH₄, this is the webinar for you!
