The Analytical Services Department of POS Pilot Plant has captured awards in four categories of the international 2007-2008 AOCS Laboratory Proficiency Program. The year-long program involved analysis of samples sent quarterly to 40 participating organizations from around the world.
POS was awarded first place in the “Phosphorus in Oil” category. This category involved quantification of phosphorus in soybean oil using ICP (inductively coupled plasma) instrumentation.
In the “Oilseed Meal Crude Fibre” category, POS tied for first place. Crude fibre is the loss on incineration of the oven-dried residue remaining after digestion of various oilseed meals with dilute sulphuric acid and dilute sodium hydroxide.
POS also tied for first place in the “Marine Oil Fatty Acid Profile” category where various marine oils were methylated to fatty acid methyl esters (FAMEs). FAMEs were quantitatively measured by GC against an internal standard. The individual fatty acids were reported in % (for all identifiable fatty acids) and mg/g (for C20:5 and C22:6).
An Honourable Mention was awarded to POS for the “Oilseed Meal Moisture” category. Moisture (and any material volatile under the conditions of the test) was determined by a gravimetric loss of weight of various oilseed meals after drying in a forced air oven.
The AOCS (American Oil Chemists Society) Laboratory Proficiency Program is the world’s most extensive and respected collaborative proficiency program for oil- and fat-related commodities, oilseeds, oilseed meals, and edible fats. Its objective is to achieve and maintain peak performance of laboratory staff and equipment so that quality control and accuracy can be maintained.
