Talk:Direct analysis in real time

message: I deleted the section about the negative ion formation process because the mechanism will not work as proposed in the article  (M* + surface ---> M+   + surface  + e-). If in this case the He metastable (denoted as M) has an energy of 19.8 eV. The ionization potential of He is 25 eV. Thus in order to get the excited He into an ionized state(denoted as M+) you would have to let it collide with the surface with at least 5.2 eV....this is under these conditions not possible, because this kinetic energy would correspond to a velocity of around 15500 m/s (approx. mach 45)!

replies: text: How about M* + surface ---> M  + surface  + e- (surface Penning ionization)? See ; the other reactions then follow.  --Kkmurray (talk) 04:55, 24 May 2010 (UTC)

Hello fellow Wikipedians,
I have just added archive links to  on DART ion source. Please take a moment to review my edit. If necessary, add  after the link to keep me from modifying it. Alternatively, you can add  to keep me off the page altogether. I made the following changes:
*Added archive https://web.archive.org/20080612122237/http://www.cbc.ca:80/correspondent/feature_051211.html to http://www.cbc.ca/correspondent/feature_051211.html
When you have finished reviewing my changes, please set the checked parameter below to true to let others know.
