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

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. Learn More
