On 27 October 2010 the proficiency test on Ethanol started with 59 participants from 24 different countries.

On that date, the samples (#1089 - #1093) 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 can be analyzed on: Acidity, Aldehyd content, Anorganic Chloride, Appearance, Density @ 20C, Nitrogen, Nonvolatile matter, Organic Chloride, pHe, Sulfate, Total sulfur, Water (coulometric), Water (titrimetric), Copper, Phosphorus, Purity , Acetone, Acetaldehyde, Acetal, Benzene,Cyclohexane, Crotonaldehyde, DEG, DIOXANE,Ethylacetate, Iso Amylalcohol, Iso Butanol, Iso Propanol,MEG, Methanol, n-Amylalcohol, n-Butanol, n-Propanol, Sec-Amylalcohol, sec-Butanol, tert-Amylalcohol, tert-Butanol, Other impurities, Permanganate time @ 20C, Purity on dry basis, Strength and UV absorbance.

The deadline for reporting results is set on 26 November 2010. 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.
