Which section of a research paper is best to state that results also depend on equipment used? I have written a paper with some interesting results. However, I would like to add one or two sentences that draw the attention of the reader to the fact that the results also depend on the instruments used for the experiment. I would like to point out, that if the equipment were more advanced, the results may be different. Do I add this information at the end of the results section, the discussion or do I add it to the conclusion? Which section is best suited for this kind of information?
I think it depends. In my opinion, it makes most sense to address equipment limitations (e.g. instrument resolution, reachable temperatures, etc.) in the method(ology) section, as was suggested by astronat. Limitations on your results, however, are more naturally addressed in the discussion (e.g. since we are resolution limited, we cannot definitively rule out alternative interpretations X, or Y, but our results are consistent with prevailing theory Z). If it is a particularly important qualifier that's central to your work, it can make sense to repeat it in the conclusion and possibly elsewhere.
