We are now set up to measure 13CO2 in exhaled breath and air samples and welcome potential research collaborators to send us samples for analyses. - No cost/fees/changes
I do not intend to charge, but would prefer the opportunity to help contribute to a manuscript with respect to methods and data interpretation. The samples would have to be in some airtight container and have a volume of >200 ml if they contain ~1% CO2 --or--- inside 12ml Exetainer vials if they contained >2% CO2.
