Individual Residue Screens

Chlorate is an effective herbicide due to the oxidative destruction of the plant tissue with release of oxygen. Chlorate was banned in herbicides in 2010 and since it's use is not permitted the maximum residue level (MRL) of 0.01 mg/kg applies. Perchlorate is a similar contaminate sometimes occurring naturally, most abundantly in deposits of Sodium Nitrate in northern Chile. Learn More

Fera is the UK National Reference Laboratory for the analyses of pesticide residues. We employ leading experts in the field to verify that food complies with regulatory requirements, ensuring consumers are not exposed to unacceptable levels of pesticide residues. Learn More

This procedure is for simultaneous analysis of chlormequat and mepiquat in a wide range of sample matrices. The methodology both identifies (screen) and quantifies residues within your food sample using state of the art liquid chromatography tandem mass spectrometry (LC-MS/MS) equipment. Learn More

This procedure is for simultaneous analyses of propylenethiourea (PTU) and ethylenethiourea (ETU) in a wide range of sample matrices. The methodology both identifies (screen) and quantifies residues within your food sample using state of the art liquid chromatography tandem mass spectrometry (LC-MS/MS) equipment. Learn More

Fera food safety experts can both identify (screen) and quantify Fipronil and metabolite residues within a food sample using state of the art LC-MS/MS equipment. We can offer this test in a range of food samples including eggs. Learn More

This procedure is for determination of Ethephon in red grapes. The methodology both identifies (screen) and quantifies residues within your food sample using state of the art liquid chromatography tandem mass spectrometry (LC-MS/MS) equipment. Learn More

This procedure is for determination of Quaternary Ammonium Compounds or QACs, as these are more commonly known. The methodology both identifies presence (screen) and quantifies residues within your food sample using state of the art liquid chromatography tandem mass spectrometry (LC-MS/MS) equipment.
