Analyte Stability
Definition
Persistence of a target under defined handling and storage conditions. A substance can change during storage, transport or processing. A stability assessment asks whether the intended result remains reliable under the actual conditions and elapsed time.
- Context
- Analytical preservation
For example, a compound detected promptly in fresh larvae may require separate stability testing before a stored specimen can be interpreted quantitatively.
A method that detects a compound in fresh larvae does not automatically remain valid after prolonged storage or in an empty puparial casing.
