SUBJECT: Proposed study to qualify use of automated isotope ratio instrumentation for stable carbon isotope ratio analysis of honey.
Method 978.17 for SCIR analysis of honey specifies use of batchwise instrumentation for the analysis: combustion and analysis are carried out in separate equipment. A recent advance in isotope ratio instrumentation is the continuous-slow automated 15N 13C analyzer , Sample preparation and analysis is completely automated and completed in about 6 minutes with no attention by the operator. This greatly reduces costs and possible errors in sample combustion and transfer of gases. There are at least 14 installations of this equipment in the U. S. and Canada, as well as many more overseas.
