Stability Of Dithiocarbamates Proficiency Test Materials

It is understandable that laboratories will be concerned about proficiency test (PT) samples for dithiocarbamates which have been in transit for several days from the PT provider. Some PT samples arrive at the laboratory having completely thawed and having the appearance of a liquid.

Fapas® has been running dithiocarbamate PTs for several years now and the process and stability of the samples is well established. This paper aims to resolve any concerns that laboratories may have on the receipt of their PT samples for this analysis.

Halal compliance for alcohol in beverages:  a quantitative PT for low concentrations

In order to be Halal compliant, foods must contain less than 1% ethanol that has been produced by natural (aerobic) fermentation. However, the level is lower for beverages, which must contain less than 0.1% ethanol in order to be classed as Halal.

In the white paper, we describe the process of including quantitative measurement of alcohol at low concentrations in the Fapas® Halal compliance in beverages proficiency tests.
