About the analytes

Multiresidues pesticides

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.

 

Why participate in a proficiency test?

There are many reasons to schedule these quality controls, the participation in international proficiency tests helps laboratories detect improvements and ensure the results are reliable.

As of today, one of the main goals for any laboratory is increase its client’s trust in their analysis procedure and results obtained, checking that equipment, personel, solvents and all the steps and parts involved in the analysis are working as intented, providing trustworthy and realiable results.

As a laboratory its is now more important than ever to be able to obtain results with precision and accuracy to help your clients commercialice products safe for the end-user.

The continuous participation in proficiency tests can help you detect bias and check if any change or improvement made as an effect on the results obtained.

How to apply and get your laboratory code

Those laboratories that want to participate and are not registered on our website can register through this link: START REGISTRATION

If your laboratory is already registered on our website you can start your application by clicking the link situated at the top or bottom of this page, in  PARTICIPATE, once you have logged in you will have to enter your Limit of Quantification (LOQ) for the parameters that have to be studied. The analytes with LOQ equal to NA (NOT ANALYSED) will NOT appear in the website when submitting the results of the PT.

Once the application has been sent, as soon as possible (usually 24h) you will receive an email with your laboratory code for the participation in the PT.

If your application is accepted and a laboratory code is granted, our compromise is that the proficiency test will be useful**.

**PT is considered useful if a certain % (internally determined according to our procedure) of present/spiked analytes will be studied.
