Control Reference Metadata

Lab Blank



Control Reference Description


Total analytical blanks are processed side-by-side with samples but without the sampled material (or use a very clean substitute for the sample, such as 18.2 MΩ-cm water).  Total analytical blanks are useful in that they reveal background levels and possible contamination for the entire laboratory process.  If total analytical blanks are sufficiently below the concentrations measured in samples, the technique is a good fit for the study.  If they reveal a significant contribution to one or more component(s) being analyzed, then troubleshooting may be necessary.
