| 术语 | 描述 |
|---|---|
| Tocolgehalt Tocol content | Mass fractions of individual Tocols determined by the procedure specified in this International Standard. The content is expressed in milligrams per kilogram as a whole number. |
| Wiederholpr?zision Repeatability precision | The closeness of agreement between independent test results obtained under repeatability conditions (same laboratory, same operator, same equipment, short interval of time). Expressed as the absolute difference not exceeded in not more than 5% of cases. |
| Vergleichpr?zision Reproducibility precision | The closeness of agreement between independent test results obtained under reproducibility conditions (different laboratories, different operators, different equipment). Expressed as the absolute difference not exceeded in not more than 5% of cases. |
| Verseifung Saponification | A pre-treatment procedure required for products containing esters of tocopherols or tocotrienols before chromatography to determine the total free content. |
| Kalibrierung Calibration | The process of establishing the relationship between the response of the measuring instrument (peak area) and the concentration of the analyte using standard solutions. |
