Are you interested in a particular PT line? Find out more about our strenght for each line:

– Veterinary Drug Residues:

Separate evaluation data for screening and confirmatory methods, with the assigned value deriving only from quantitative confirmatory results. This feature of our PTs respects the requirement of UNI CEI EN ISO/IEC 17043:2010 to use fit-for-purpose methods of evaluation, makes the assigned value more reliable and the assessment more valid. Even if you are using a screening method, the PT simulates what you would do in the routine (comparing your results with confirmatory ones). The semi-quantitative (< or >) and qualitative screening results receive evaluations provided with dedicated criteria. The quantitative screening and confirmatory results are evaluated through z-score.
More reliable assigned value due to more stability of Test Materials. Most of them are provided as lyophilized (to be tested after reconstitution). In this way, regardless of the provenience of the laboratory, every participant can be sure to receive the Test Material in the same conditions. Once reconstituted it is the same as in your routine!
We generally offer many different matrices for Veterinary Drug Residues such as: muscle (swine/bovine/turkey/hen/chicken/rabbit), liver (sheep/bovine/swine), gut, eggs, urine (bovine/swine), bovine milk, bovine serum, fish, shrimps, animal watering water, medicated and non-medicated feed, light honey…
Mainly multi-contaminated materials are provided. Several molecules of the same family or several families will be present in the same PT.
In some cases, the participation provides 2 different Test Materials, (they can be both contaminated or one of them could be blank). In the PT, as in the routine, the laboratory technicians do not know if they are testing a contaminated or a blank material. In this way, the laboratory could be assessed also for False Positive results or for method performances at different levels of concentrations.
Information about False Positives is provided in the Final Report.
Whenever possible we provide incurred (naturally contaminated) Test Materials that allow to evaluate the method extraction capability.
Often Niche PTs are offered: check our proposal, you will often encounter PTs difficult to find on the market!
For some combination matrix/analyte they are also available some materials characterized as blank, also to be purchased together with the PT.

– Freshness parameters:

Convenient fee: 2 Test Materials for histamine are included. You will be evaluated at different concentrations levels with only one subscription! So, with our PT the convenience doubles: you will receive 1 Test Material with High Level of Histamine and 1 Test Material with Low Level of Histamine.
Furthermore, it is possible to submit 2 sets of results: with just one subscription you can evaluate 2 laboratory technicians, or 2 different techniques. Both results will be evaluated in the Final Report. So, for histamine you can send up to 4 results!
Separate evaluation data for screening and confirmatory methods for histamine, with the assigned value deriving only from quantitative confirmatory results. This feature of our PTs respects the requirement of UNI CEI EN ISO/IEC 17043:2010 to use fit-for-purpose methods of evaluation, makes the assigned value more reliable and the assessment more valid. Even if you are using a screening method, the PT simulates what you would do in the routine (comparing your results with confirmatory ones).

In this way, regardless of the provenience of the laboratory, every participant can be sure to receive the Test Material in the same conditions. Once reconstituted it is the same as in your routine!
For Histamine incurred (naturally contaminated) Test Materials are provided to allow method extraction capability evaluation. When planned, also for Biogenic Amines and TVBN, incurred Test Materials could be provided.

– Mycotoxins:

Mainly natural multi-contaminated materials are provided. Incurred (naturally contaminated) Test Materials allow to evaluate the method extraction capability.
Separate evaluation data for screening and confirmatory methods, with the assigned value deriving only from quantitative confirmatory results. This feature of our PTs respects the requirement of UNI CEI EN ISO/IEC 17043:2010 to use fit-for-purpose methods of evaluation, makes the assigned value more reliable and the assessment more valid. Even if you are using a screening method, the PT simulates what you would do in the routine (comparing your results with confirmatory ones). The semi-quantitative (< or >) screening results receive evaluations provided with dedicated criteria. The quantitative screening and confirmatory results are evaluated through z-score.
Generally we offer many different matrices for Mycotoxins: cereals (maize flour, wheat), nuts (peanuts, nuts, almonds, pistachio), green coffee, milk, apple juice, wine, dried fruit, feed…
Often Niche PTs are offered: check our proposal, you will often encounter PTs difficult to find on the market!

– Contaminants by process (Acrylamide, IPA and others):

For Acrylamide real process contamination Test materials (not spiked). The laboratories must prefer this kind of Test Materials instead of spiked ones, to evaluate the method extraction capability.
Separate evaluation data for screening and confirmatory methods, with the assigned value deriving only from quantitative confirmatory results. This feature of our PTs respects the requirement of UNI CEI EN ISO/IEC 17043:2010 to use fit-for-purpose methods of evaluation, makes the assigned value more reliable and the assessment more valid. Even if you are using a screening method, the PT simulates what you would do in the routine (comparing your results with confirmatory ones).

– Metals:

More reliable assigned value due to more stability of Test Materials. Most of them are provided as lyophilized (to be tested after reconstitution). In this way, regardless of the provenience of the laboratory, every participant can be sure to receive the Test Material in the same conditions. Once reconstituted it is the same as in your routine!
We generally offer many different matrices for Metals: vegetables, muscle, liver, fish, milk, powdered eggs, honey, legumes, water, feed, table salt, tomato puree, wheat flour, dried mussels, beer…
