Disambiguation

edit

Someone should make a note that electron capture detector should not be confused with another ECD: electron capture dissociation. "Electron capture detector" refers to a detector in a gas chromatograph, whereas "electron capture dissociation" is a technique to generate ions for mass spectrometry.

fg/s

I don't see any value in starting down the road of creating articles for every unit of measure out there. The "femto" prefix is uncommon, but "g" for grams and "s" for second are pretty common. Therefore, I removed the wiki-link for "fg/s" and just wrote it out instead. Pi3832 16:27, 23 May 2006 (UTC)Reply

electrons - need clarification

edit

this sentence :

"The electrons are formed by collision with nitrogen because nitrogen exhibits a low excitation energy, so it is easy to remove electron from nitrogen molecule. "

The electron comes from the radioactive emitter, that why it is used... so what does this sentence mean ? The collision between nitrogen and what ? I'm not saying it is false, but it needs to be clarify. —Preceding unsigned comment added by Akry39 (talkcontribs) 18:48, 22 July 2009 (UTC)Reply

I agree. The sentence is very confusing. What happens is that the primary electron from the radioactive source releases many more electrons by collision with nitrogen. But I don't understand how the carrier gas that contains no nitrogen is supposed to work. Needs attention from an expert.Petergans (talk) 14:30, 13 April 2010 (UTC)Reply
I improved the text to make this clear. Carrier gas and makeup gas are not the same. — Preceding unsigned comment added by 81.62.186.127 (talk) 14:05, 15 July 2011 (UTC)Reply
