About the analytes

 

The pesticide control is a rutine analysis very important for the assurance of the security of the food and compliace of it with the legislation. Laboratories must be able to detect and quantify correctly between hundreds of possible pesticides if an analyte is in the sample and in which concentration, always avoiding reporting false posivites.

The Maximum Residue Limits (MRL) for the pesticides is the maximum amount of pesticide that should contain a matrix in order to not be a health problem for the consumers, to facilitate its comercialization and to control the use of phytosanitary products. The decision to set the MRL takes into account a wide number of variables, to cite some: toxicologic data, metabolism and the persistency in various environments.

The MRL can be consulted in the annexes from the reglament 396/2005 here and an updated list of pesticides and their MRL for each matrix can be found here.

You can see the possible pesticides in the sample by checking the protocol that can be found and downloaded in this page.

 

Summary of the proficiency test

 

All the information about this PT can be found in the protocol, which can be donwloaded from a link located in the right column in this page. 

This proficiency test will consist in a single round, two samples will be distributed, depending on the order placed.  You can check the amount of sample each participant will receive in the protocol of this proficiency tests.  If needed and justified, more amount of sample can be requested to the coordinator of the PT. Additional charges might apply.

The range of concentration for the target analytes of this proficiency test might by between 10 and 200 μg/kg approximately.

For this PT the possible target analytes can be found in the protocol.

The target standard desviation for all the analytes is 25%.

 

IMPORTANT:

All analytes left as NOT ANALYSED (NA) in the application will not be asked when reporting the results.

In a proficiency test in which the analytes must be detected and quantify from a possible target list of analytes, laboratories have a perfect chance to show to their clients the capacity to make a scan of any sample and be able to detect and correctly quantify the present analites while avoiding false positives.

TestQual's proficiency testing schemes are a useful tool for testing laboratories to demonstrate their competence and quality assurance of their analysis, a continous participation allows our clients to compare their results with other laboratories from the sector, follow up their performance and detect bias or errors that can be correctly approached with preventive or corrective actions.

 

By assiduously participating in PTs laboratories can assure their clients their commitment to the continous improvement and scaning of possible errors, offering always the security and trust that their results are always reliable and have been contrasted through an exhaustive internal quality control and continuous checks with the participation in TestQual's proficiency tests.

Additionally, from TestQual we make sure to listen to all the feedback given by our clients, making sure our PTs are designed accordingly with the needs and sugestions of our participants.
