Summary of this proficiency test:

On 4 September 2013 the proficiency test on Mixed Xylenes started with 37 participants from 21 different countries.

On that date, the samples were dispatched to the laboratories. Enclosed to the samples were the instructions to the participants for this proficiency test, forms for the reporting of the analysis results and the material safety data sheet (MSDS).

The samples have to be analyzed on: benzene, Toluene, P/M/O Xylenes, Ethylbenzene, Cumene, sum of non aromatics, sum of C9 and heavier aromatics.

The deadline for reporting results is set on 4 October 2013. A laboratory that sends in results after deadline will definitely not get direct feedback in case any of its results are suspect! So be in good time to get the most out of this proficiency test.
