Okay, these are analysis numbers, not sample numbers, per se.
This is not good control, by the way, but that's a different
question. Samples should be labelled and then correlated with analysis.
Now, what we know is that the two samples were analyzed on the same
day. How long was this experiment? So they held the sample from
"before" and analyzed it only later? Was this a sample of the same
material or of similar material?
I keep coming up with more questions, because the exact procedures
used have not been stated. The paper is actually quite short on
specific information, and long on theoretical explanation, which has
a high probability of being utterly irrelevant.
I.e., what they actually did to change the material isn't stated,
only some theoretical result.
And on and on.
My point is that this isn't "scientific information." It's a
commercial report, heavy on "meaning" and light on "what happened."
(I did not claim that there was "wrong labelling," only that I
couldn't tell what had happened.)
The comment quoted below about "on different days" is mysterious,
since the samples, labelled per Defkalion comment, show the same day.
I'm not sure at all why they used those sample numbers, since they
tell us nothing about the *samples*, but only about the *analytical batch.*

Yes and on different days. This is what PDGTG said in response to
the question.

"XRF devises (sic), such the ones we use, label the measurements
automatically per day, maintaining a sequential number. We perform
such analysis in batches having labeled the samples before and after
the reactions. So there is not any discrepancy or wrong labeling in
this case."
