As part of ensuring a constant quality control and -improvement, Primoris takes part in many national and international ring tests. These are independent checks on the quality of laboratory analysis. Based on the results of these ring tests, the performance of the analytical method is evaluated and, if necessary, improved. There is deliberately opted for 'difficult' ring tests, with the aim to achieve quality improvements where needed.

Primoris took part in following ring tests:

- CODA CERVA: ring test on mycotoxins on barley
- PROOF-ACS: method ring test on dithiocarbamates on pear and strawberry
- FAPAS 1656: ring test on patuline on apple juice
- FAPAS 1269: ring test on melamine on a food simulant
- Relana undercover sample: pesticide residues on raspberries
- Relana undercover sample: pesticide residues on chia seeds
- FAPAS 15106: ring test on pesticide residues on lettuce.

Primoris is included in the Relana® quality circle of European laboratories. Relana stands for “reliable analysis” and was founded with the aim to ensure the quality and integrity of performed analysis within the food chain.

Primoris Belgium, as one of the selected laboratories, must meet the highest possible standards of expertise based on compliance with premium quality guidelines for residue laboratories.

“Living analytical competence”: "Not only during an audit or on paper - but especially in the daily routine."

Annual audits, the use of undercover ring test samples and constant evaluation of competence and customer support levels are just some examples of how the highest possible guarantee on reliable analysis and high quality support can be pursued.

The results of these ring tests are available to our customers and can always be requested.
