| Definitionskos:definition | A specimen blank is used to determine if any impurities are introduced during sample preparation procedures. A "sample blank material" substitutes regular "sample material" in the procedure. Example 1: Quartz substitutes a rock sample to determine levels of impurities introduced by grinding equipment. Example 2: Cellulose substitutes vegetable material to determine levels of impurities introduced during sample preparation. Example 3: Pure deionized water is substituted for sample water to determine if impurities are introduced during sample filtering and bottling procedures. |
