Hi Hötzi,

» I don’t see how that can affect the IS (and analyte) response unless someone works with peak heights (who does it nowadays?)…

As a general rule the S:N become more unfavourable as the column ages and peak separation suffers. This affects the identifcation of peaks and their integration. It will be more pronounced for the analyte near the LLOQ than for the IS.

I could be wrong, but...

Best regards,
ElMaestro

R's base package has 274 reserved words and operators, along with 1761 functions. I can use 18 of them (about 14 of them properly). I believe this makes me the Donald Trump of programming.
