Which reagent is best among 'Dimethylglyoxime" and "Dithiothreitol" for spectroscopic determination of Nickel ?

What I think is Dithiothreitol. As it is water-soluble and does not form a precipitate. But, the thing is it contains sulphur which is quite hazardous to aquatic animals.

This is the same as removing the DC globally and then scaling the signals, so there's no intrinsic problem there in my opinion.

But if you compare different conditions, then it is a relative power spectrum, so a change in a higher-frequency band could be driven by a change in a lower-frequency band.
