We encourage you to read our Sample Analysis Policy to ensure you qualify to have your samples analyzed in IsoLab.

The below rates are per analysis, not per sample. Some methods require replication of a single sample before data become usable. Sometimes data are not particularly useful to a researcher because they don’t show an anticipated pattern or, perhaps, don’t even contain the analyte of interest. Assuming the analysis proceeded without failure, researchers are still responsible for the cost even if the data are not what they expected or are marginally useful to their question.

The sample analysis cost reflects the actual cost for a single analysis. It includes all materials and labor for that one single analysis. It inherently assumes that the instrument used and person employed are tools and can be turned off and placed on a shelf when the analysis is complete. This, of course, is certainly not the case for a person. As such, the analysis cost may not cover the true cost of employing a person. Academic labs typically have a subsidy that covers the cost of keeping technicians employed when they are not analyzing samples. Furthermore, our sample cost schedule must be a good faith estimate of the costs associated with a single analysis, as per the University of Washington. We must assume that the instrument has only nominal dormancy, otherwise sample costs could be radically inflated if, for example, only a single analysis of a particular method was completed in a single year. Commercial labs simply charge more per analysis to cover the instrument dormancy.
