Recognizing that laser-based isotope-ratio-measurement systems can produce 
large amounts of data, I requested that the two manufacturers, Los Gatos 
Research (LGR) and Picarro, make their instruments available for use in 
teaching LIMS for Light Stable Isotopes in Vienna in April, and they 
kindly did so.

It has come to my attention that some individuals have misunderstood the 
purpose and objectives of this workshop. Therefore, I am sending this 
email to clarify my intent. WE WERE CONDUCTING ONLY A TEST OF SOFTWARE 
COMPATIBILITY, NOT AN ANALYTICAL PERFORMANCE TEST. 

Indeed, this workshop was NOT a head-to-head performance comparison test 
of instrumentation, and potential purchasers of laser-based 
instrumentation would be foolish to think otherwise. Readers SHOULD NOT 
use the analytical results obtained during this workshop to make 
procurement decisions. Manufacturers were not given the opportunity to 
optimize their instruments for a performance test.

The purpose of inviting multiple manufacturers of laser-based 
instrumentation was to demonstrate that LIMS for Light Stable Isotopes is 
now compatible with the latest versions of their software, and this 
demonstration was fully successful. In previous demonstrations, LIMS has 
been shown to be compliant with ISODAT, MassLynx, and IonAdvantage as 
well. 

Finally, please note that use of trade, product, or firm names in this 
email is for descriptive purposes only and does not imply endorsement by 
the U.S. Government.

If you have any questions about the measurement results, conclusions, or 
LIMS, PLEASE contact me directly.

Thanks,
