Here’s the notice for “Achievement of 1.4 ng detection limit of cesium with TXRF spectrometer by changing the X-ray detector and reducing noise:”
We the authors Susumu Imashuku, Deh Ping Tee, Hiroko Seki, Hiroya Miyauchi, Osami Wada and Jun Kawai hereby wholly retract this Journal of Analytical Atomic Spectrometry article due to the way the data was presented, in order to maintain the accuracy of the scientific record. Signed Susumu Imashuku, Deh Ping Tee, Osami Wada and Jun Kawai, Kyoto University, Kyoto, Japan, Hiroko Seki and Hiroya Miyauchi, Kyoto Prefectual Technology Center for Small and Medium Size Enterprises, Kyoto, Japan, July 2013. This retraction is endorsed by May Copsey, Editor. Retraction published 19th July 2013.
We asked Kawai for details, and he told us:
Imashuku, the main author, found something error in the Table in the paper at the proofreading, and he would like to replace it or remove it.
He said it to the editor, but the editor requested again the referee process. And he put the paper as it was until today. The paper you inquired was very important paper and thus I have just pushed him to try again.
This of course doesn’t really help understand what was wrong with the paper, nor the timing. The paper was first published online on February 13, 2012. When did the proofreading happen, and why was the study retracted more than a year later?
The fact that the editors wanted to send the study out for peer review again makes us wonder even more. We’ve asked editor Copsey for comment, and will update with anything we learn.
