Making samples for proficiency schemes

We are involved in the running of several analytical proficiency schemes, in which test samples are sent to laboratories so that they can evaluate their ability to analyse it. We also have many years' experience in the manufacture of scheme reference samples. Drawing on industrial experience and using an extensive range of equipment in our process halls, we work closely with scheme providers to manufacture a range of reference test materials.

We can advise on suitable formulations, make bespoke products with spiked amounts of measurand (the analyte being measured) and evaluate the most suitable processing conditions to ensure stability of the reference material. Some test materials can withstand thermal processing, some require freezing, some are preserved by other means; the preservation of the test material is often dictated by the stability of the analyte being tested, e.g. sodium metabisulphite would be destroyed during thermal processing.

We have experience in the manufacture of a range of food and drink products incorporating measurands at very low levels, e.g. vitamins, to much higher levels.
