Dear all,

my institute is  considering to purchase a CRDS instrument in order to 
analyse d13C of CO2 in gas samples from soil incubations. We are 
planning to connect the instrument to an automated microcosm system, 
where the analyser is needed to monitor d13C of CO2 in the exhaust flow 
from the microcosm which are continuously flushed with a carrier gas at 
approximately 20 mL per minute. So the instrument must be able to 
analyse at such low flow conditions. As far as I can see there are two 
companies (Los Gatos, Picarro) offering instruments for real time 
monitoring of d13C of CO2. The question is which one would be preferable 
for our application?

We would greatly appreciate any information to support our decision.

Reinhard
