Self test 8.1

Short-term stability is evaluated for sample storage conditions and transportation.

Long-term and freeze-and thaw stabilities help to plan sample storage conditions and interruption on sample transportation. 

Stock solutions are stable and their stability should not be evaluated during the method validation.

If the analyte is stable in the standard solution then the analyte is also stable in the sample.

Sample stability during the accidental breakdown of the LC-MS instrument can be evaluated with on-instrument/autosampler stability.

Analyte stability depends on temperature and illumination.
