Measurement Uncertainty for Chemistry & Microbiology

Abstract

Labs making chemical and/or microbiological measurements have long been left out of the measurement uncertainty discussion at major physical metrology conferences. As a result, calculating measurement uncertainty for chemical and microbiological analysis can leave many physical metrologists scratching their heads in wonder. The rules we have learned for calculating electrical or dimensional uncertainties do not transfer as smoothly. The good news is that there are proven methods and guidance how to calculate measurement uncertainty for chemical and microbiological measurements. There is also guidance on what to do when measurement uncertainty cannot be calculated.
