Maren Oelbermann

I suggest you contact Claudia Wagner-Riddle at the University of Guelph. I know she has used tunable diode laser for 13C CO2. I am not sure if she has used this method for other applications, however. It would be worth wile to give her a call: https://www.uoguelph.ca/ses/users/cwagnerr
