Pesticide residue testing
QTS has developed state of the art analytical techniques to provide a first class residue testing service in a wide range of commodities. We have made a considerable investment in development and are very pleased to have available the following techniques:

Multiresidue:
This technique provides a screen for over 200 residues, it tests for a wide range of residues from numerous pesticide groups including Organochlorine, Organophosphate, Organonitrogen, Triazine, Carbamate, Triazole, Dicarboximide, Strobiluron, Pyrethroid and many others including post harvest treatments traditionally tested for separately.
Almost all of these residues are tested with a reporting limit of 0.01mg/kg or 10ppb and turnaround available for this test is from a staggering 12 hour service to our standard 5 day service.

Dithiocarbamates:
We have developed a new automated technique for the testing of dithiocarbamate residues, the technique has been specially designed to minimise false positives, a problem that has long plagued traditional dithiocarbamate techniques. We have successfully developed a technique that can not only provide results in a matter of hours but also has reduced the risk of false positives dramatically.
Our reporting limit for Dithiocarbamate residues is 0.05mg/kg, turnarounds for this test also range from the 12 hour service to the standard 5 day service.

Carbamates, Benzimidazoles, Neonicotinoids, Spinosad, Abamectin & Others
One of our recent developments has been to develop a new technique that combines several traditional techniques into a single test, this allows for a substantial increase in coverage without a substantial increase in cost. Traditionally and currently tested separately by most other labs, this would cost over £200.00 elsewhere, due to the huge advance in the technology and technique we use we are able to offer this whole screen for £50.00 per sample without any compromise to the quality.
Our reporting limit for the residues in this list is 0.05mg/kg, turnarounds for this test also range from the 12 hour service to the standard 5 day service.

A full list of the residues covered in the screens is available from our customer services department.

Other Residue Testing
We routinely carry out many other types of residue testing, following is an outline of some of the most commonly requested tests:

      “Quat Screen” – provides results for Chlormequat, Mepiquat, Diquat and Paraquat
      in a single screen.

      Glyphosate

      Organotin

      SO₂

      Maleic Hydrazide

      Tartaric and Malic Acid

      2,4-D

We are able to carry out these tests on a wide range of commodities from fresh produce to processed foods and drinks, if you have a testing requirement that is not listed please contact us as it is quite likely that we already offer it but do not have it listed.
