| blank | |||
| Material which contains no, or as little as possible, of the analyte of interest, used in measurement to establish a blank indication | |||
| Note 1: | Testing, processing and measurement of blanks are nearly always an essential part of chemical analysis and may be part of quality assurance and quality control. See ref. 15 p. 130. | ||
| Note 2: | The concept may be extended to more than one analyte. | ||
| Note 3: | Terms such as “solvent blank”, “reagent blank” or “matrix blank” are often used to specify the material type of blank. | ||
| Note 4: | The term “procedure (or procedural) blank” is often used to denote a material that is carried through the entire measurement procedure. Terms such as “field blank”, “calibration blank” and “instrument blank” refer to materials handled in specific parts of the procedure. | ||
| Note 5: | A blank to which a relevant component has been added is often termed “spiked blank” or “fortified blank”. Compare spike, internal standard and measurement procedure with standard addition. | ||
| Note 6: | If the term “blank” is used, e.g., to denote the blank indication or the related blank value or blank correction, this must be clarified by the context. | ||
