September 2007[edit]

what is "m/z"? —Preceding unsigned comment added by 212.213.154.74 (talk) 13:28, 5 September 2007 (UTC)[reply]

'm/z' stands for 'mass to charge ratio' I'll check that and try to clarify. Leafschik1967 01:47, 6 November 2007 (UTC)[reply]

March 2011[edit]

What do you mean 'highly parallel'? Either the rods are parallel or they are not. If it is not 180 degrees, specify the angle. 24.54.107.103 (talk) 02:06, 1 March 2011 (UTC)David Kreller[reply]

I didn't write that but there are actually cases where they are not parallel on purpose. [1] it should probably read "generally parallel".--Nick Y. (talk) 19:17, 1 March 2011 (UTC)[reply]

WikiProject class rating[edit]

External link[edit]

The External Link actually refers to a password protected page, which is not of very much interest to the general reader. 88.98.33.193 (talk) 16:50, 10 November 2014 (UTC)[reply]

Removed. Also, if it was this page [2], it fails WP:ELNO #1. --Kkmurray (talk) 22:37, 10 November 2014 (UTC)[reply]

May 2016 - history and noble prize[edit]

The article is missing a reference to Paul Wolfgang, the inteventer of the quadrupole in 1953 https://en.wikipedia.org/wiki/Wolfgang_Paul

Feb 2020[edit]

I created this image for my thesis, perhaps it can be of use.

mixup[edit]

The article mixes up the ion selector inside a QMS (= the quadrupole mass analyzer) and the QMS themselves. SCIdude (talk) 15:22, 30 October 2022 (UTC)[reply]
