CN-EA-iRMS results guide
A CN-EA-iRMS results file includes up to four tabs. A results summary is in the fourth and last Final Report tab.
All data are observed directly and recorded by Thermo Scientific Isodat software during automated analysis. This output is recorded in the first Export tab. These C and N data are normalized (also called corrected) to international reference scales according to the calculations explained below. These calculations are documented in the second and third C and N Corrections tabs. A comprehensive understanding of the contents of the first three tabs is generally unnecessary for appropriate application of CN-EA-iRMS results in the results summary in the Final Report tab.
Quality control (QC) standards are standard reference materials with measured and normalized with identical treatment of standard materials. These results are checked for internal consistency (precision) and external consistency with established calibrated or reference values (accuracy). Any CN-EA-iRMS run at UCSC SiL will include IU Acetanilide, and some runs may include USGS41, 61, 62, and/or 63.
