Determination of Pesticides in Grapes, Baby Food and Wheat Flour by Automated Online Sample Preparation LC-MS/MS

Instrument Type: LCMSMS

European Regulation 396/2005 sets maximum residue levels of pesticides in different products of plant and animal origin. These regulations present a significant analytical challenge with respect to LOQs required for some specified food matrices such as baby food. The multi-residue pesticide method described can be applied to fruits, cereals and composite baby foods at LODs in the range of 0.8–10.3 µg/kg - below respective EU maximum residue limits (MRLs). The method is validated for 48 pesticides from different classes, but can be readily extended to a larger number of residues.

Determination of Carbendazim and Benomyl Residues in Oranges and Orange Juice by Automated Online Sample Preparation Using TLX-LC-MS/MS

Instrument Type: LCMSMS

Methyl 2-benzimidazole carbamate, most commonly known as carbendazim, is a widely used broad-spectrum benzimidazole fungicide and a decomposition product of benomyl. Carbendazim is used to control plant diseases in cereals and fruit, including citrus, bananas, strawberries, pineapples, and pome fruits. We describe a method that is an adaptation of an existing online, multi-residue pesticide method (Thermo Scientific Method 522133) proven and verified specially for the actual carbendazim contamination issue of orange juices in the US.

Validated Method for the Determination of Phenylbutazone in Horse Meat with LC-MS/MS

Instrument Type: LCMSMS

Phenylbutazone (bute, PBT) is one of the most widely used (non-steroidal) anti-inflammatory (NSAiD) and painkiller drug for dogs and horses. Horse meat is still widely used for human consumption in some European countries. For those animals marked for human consumption, a limited number of medicines can be administered. A newly developed LC-MS/MS method for the determination of PBT in horse meat with LC-MS/MS is described here. The method was validated in-house and its applicability for routine testing was tested following the European legislation requirements.
