Subject field(s)
  • Analytical Chemistry
DEF

"reagent blank": a solution or mixture of all reagents used in an analysis, treated in the same way as the sample but without the sample analyte present; provides a baseline correction to the result of the analysis.

OBS

In any chemical or other scientific experiment, the reference base with which the results are compared. This base is invariably a sample of identical constitution and prepared under the same conditions, from which all experimental variations are omitted. Thus the control represents known values, as far as any specific experiment is concerned. Such a sample is often called a "blank". The use of a control is vital to significant interpretation of experimental data.

OBS

See also "blank test" in Termium.
