[Correction] you cannot report area% to two decimals off that baseline
Not naming the poster, the trace is in the thread below this one and they will know. The reported figure is 98.47%. The baseline in the attached trace drifts visibly across the run and there is noise of roughly the same magnitude as the smallest reported impurity. You cannot resolve a hundredth of a percent off that.…
the same instinct applies to weighing. an analytical balance reading to five places does not mean your sample mass is known to five places once you have opened the door.
yes, and it is the same failure — trusting the display over the process.
if your baseline wanders your integration lies, and every digit after the first decimal is the lie getting more confident.
