"...to ensure passing system suitability results."

Validation is to show suitability for the intended purpose. Mission accomplished!

I never would have imagined to see erosion of all what we call "science" in such a short time...

Last night some idiot presented somewhere in the world a chronically ill person and her father into public to advocate "faster approval" of what-so-ever-idiot-calling-himself-a-scientist-has-pulled-out-of-his-axx as a drug by the FDA.

Generally system suitability could be performed to assess whether the system runs within its spec’s before an analytical run (CCs, QCs, unknowns). Examples: Injecting blank extracts to condition new columns, checking retention times, capacity factors, peak symmetry & resolution, tuning the detector, :blahblah:
Of course, a procedure must exist and followed. Limiting SS to a certain number of injections is not a good idea. Deleting out-of-spec’s results is stupid. Better is sumfink like:

“The system suitability test passes if – after corrective measures if necessary – n subsequent (!) injections fulfill criteria X, Y, Z.”


Fully agree to your other points. :-D
Didn’t Mr Trump say that for every new regulation two old ones have to be suspended? Lean state?

 System suitability

I once heard that a chinese company conducted a replicate study with n=24 and ran the stats as if it was a n=48 subject study... Not a joke...:confused:
