What is the labboratory test used to detect traces of potassium bromate in breads ?

Dear lapatisserie-ga;

Thank you for allowing me an opportunity to answer your interesting
question.

The method used to test for flours and breads for traces of potassium
bromate is called “inductively coupled plasma-mass spectrometry (CV of
12%)”, sometimes called “closed-vessel microwave digestion with flow
injection–inductively coupled plasma–mass spectrometry”. This method
replaces two older, less accurate tests called “Gas chromatography (CV
of 18%)” and “Liquid Chromatography with Post-Column Flow Reactor
Detection PVM 2:1999”.

Below you will find that I have carefully defined my search strategy
for you in the event that you need to search for more information. By
following the same type of searches that I did you may be able to
enhance the research I have provided even further. I hope you find
that that my research exceeds your expectations. If you have any
questions about my research please post a clarification request prior
to rating the answer. Otherwise, I welcome your rating and your final
comments and I look forward to working with you again in the near
future. Thank you for bringing your question to us.

Best regards;
Tutuzdad-ga

Sir,
Can this test be explained in a step-by-step procedure with the test bread samples?

Dear lapatisserie-ga; 

Unfortunately the procedure itself is well beyond my area is expertise
as a researcher and would likley require the knowledge of someone who
has a relatively high academic degree in chemistry and (probably) who
also specializes in this type of testing. The information I supplied
comes merely from records found during a search for the answer of your
original question, though some of the links may describe these methods
in some detail.
