I can't comment on their QA/QC, turnaround time, etc. >I am looking for laboratories with municipal solid waste experience >that do stable isotope analyses as well as carbon-14 and tritium. >At this point I would like to find commercial labs that can >consistently meet turnaround times, as I know university labs >sometimes may have a problem with this. We have already done some >analyses with one lab, but would like to get a short list of labs >together to audit early next year. > >I am interested to hear from you regarding your lab, its >capabilities, and average turnaround time.
