Processed Sample Stability [Bioanalytics]
❝ Processed Sample (PS) Stability proved at 10°C (In Auto-sampler), Can we analyze the processed Samples which were stored in refrigerator (4°C) for which stability was not established at refrigerator (4°C) condition.
What are your thoughts – do you remember the Arrhenius equation? However, in the strict sense (!) autosampler stability ≠ processed sample stability.
This reminds me on heated discussions at the Crystal City III workshop along these lines:
“We have validated long-term stability at –20℃.
Can we store samples at –70℃ without re-validation?”
Was – and is – beyond my intellectual reach. See also Ohlbe’s post.
