Dear friends,
the Rietveld mailing list has been used for several purposes. To ask for
advice, to share information, to enjoy talking about crystallography.
Sometimes, however, it brought sad news, like is doing today.
J Ian Langford, almost 80, passed away last Sunday after being taken into
Enyuan
There are two carbon copy versions of that 1915 paper, one appearing in
Nachrichten von der Koeniglichen Gesellschaft der Wissenschaften zu Goettingen,
Mathematisch-Physikalische Klasse Heft 1 (1915) 70-76
And the other one in
Annalen der Physik 351 [6] (1915) 809-823
The paper is in
I guess you are talking about detection limit only, not quantification limit,
right?
The answer largely depends on your material (scattering power, domain size),
tube (sampling volume) and counting time. I have seen cases where you can
clearly see something below 0.1 wt% and cases where already
veld standard uncertainties of QPA are underestimated about
> 2-3 times.
