Equipment status should be established before use where applicable.
An instrument that is marked out of service should not be used simply because it appears to be functioning.
7. Prepare the Sample Correctly
Equipment cannot compensate for poor sample preparation.
Depending on the procedure, sample preparation may involve:
- Correct identification
- Measurement
- Dilution
- Mixing
- Filtration
- Centrifugation
