what is "m/z"? —Preceding unsigned comment added by 212.213.154.74 (talk) 13:28, 5 September 2007 (UTC)
 * 'm/z' stands for 'mass to charge ratio' I'll check that and try to clarify.  Leafschik1967 01:47, 6 November 2007 (UTC)

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


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

I created this image for my thesis, perhaps it can be of use. Gadolinq (talk) 16:59, 9 February 2020 (UTC)

mixup
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)
