Stingc,
I am
not worried about isotopes. In fact, my initial position is that there
will be an isoelectric equalibrium in the human system.
Lebell,
It is akin to assigning charge numbers to elements (ie. Na 2+ being the same as Na +2). P+ simply means that there are more protons than neutrons as a result of nuclear chemistry in action.
A-ray fluorescence spectometry .. cool development in analytical chem! I've read a few journals regarding XRF and VOC detection - hell of a lot better than doing combustion analysis!
In any event, physical theories asside ... with 3 sig. figs of precision, any imbalance in N+ and neutral isotopes present is well within the error range afforded. You may not agree with my method .. however, surely you can appreciate that it is both: more elegant, and more reliable than calculating percent composition, etc .. and then finding the number of e- present from the derived data.
