Summary of this proficiency test:

On 30 January 2013, the proficiency test on MTBE started with 17 participants from 14 different countries.

On that date, the samples were dispatched to the laboratories. Enclosed to the samples were the sample receipt form for the participants to return upon receipt and the safety data sheet (SDS).

The MTBE samples have to be analyzed on: Appearance, Water, Carbonyls, Refractive index, Density @15C, Purity, Purity on dry basis and some GC- impurities: Diisobutylenes, Methanol, t-Butanol, C4-, C5- and Other hydrocarbons.

The deadline for reporting results is set on 1 March 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.
