Thanks for the positive feedback on mass-to-charge ratio etc. I am still a little concerned about the common usage of this term and the prefered units in the electron optics and related (i.e. non-mass spec) fields. In my limited experience in pure electrodynamics (non-MS) I remember solving problems involving m/q but do not remember using Da/e. I think this needs to be validated. I can't find it in the literature with a quick search but then it is a hard search term. Additionally, although I know that m/q enters into teh physics of many of teh fields listed (other than mass spectrometry) I have yet to see evidence that there is use of the term "mass-to-charge ratio" in these fields or that it is somehow notable. In fields that involve electron optics I see no advantage to using Daltons, and no point in stopping at the m/q relationship since the mass and the charge are known. Why not just solve the problem and be done. Accelerator physics and ion optics I get stopping at m/q. I still would think that for the most part SI units would be more handy.--Nick Y. 17:26, 2 October 2006 (UTC)
