Review
[edit]The article is good in general. The author devotes a lot of efforts to extend the article, such as the emitters, sample loading techniques and field desorption mass spectrometry and so on. I appreciate her contributions to this article. However, there are some minor mistakes need to be corrected. At first, I checked this article and there are several typos and grammar mistakes. According to my understanding, you seemed to misspell several words. Please replace " well defined" with "well-defined", " filed" with " field", "accrately" with " accurately" and "formaiton" with "formation". The noun phrases "well-defined geometric shape,"negative ion", "sample", " analysis", " internal standard" seem to be missing determiners before them. Please consider adding an article before them. Secondly, the structure needs to be rearranged. I think it's better to combine the liquid injection with the other sample loading techniques in some way. And it's a good idea to change the title from " field desorption mass spectrometry" to " field desorption modes". Finally, the supporting materials are comprehensive and the author added several reliable sources.
FD vs FI
[edit]Field Desorption and Field Ionization are two different effects, the assumption that both are the same were already proven to be wrong in the early 60s! FD was discovered by Müller in 1941, as stated in the referenced book by Beckey. FI was first discussed in 1928 by Oppenheimer and observed in 1951 by Müller. As stated in Müller and Tsong, 1973, Field Ion Microscopy, Field Ionization and Field Evaporation Field Desorption requires the preceding adsorption of the analyte on the electrode surface. Field Ionization ionizes the atoms/molecules of a gas at very low pressure using electron tunneling inside a sufficiently (1-10 V/°A) strong electric field and cannot occur below a critical distance x_c of the emitter. — Preceding unsigned comment added by Leticron (talk • contribs) 17:08, 8 February 2013 (UTC)
>>I've removed all instances of "FI" in the page but lack the proper understanding to create it's own page. I second the above commenters assertion that FD and FI are separate techniques and that FD/FI is a misnomer
