An assay was developed here that leveraged the sensitivity of the SCIEX Triple Quad 7500 system to quantify all Health Canada regulated pesticides. Using high sample dilution and small injection volumes, ionization suppression was significantly reduced, which allowed for accurate quantitation without the use of matrix matched standards or correction with internal standards. APCI was used in addition to ESI for improved analyte coverage or sensitivity enhancement for challenging analytes.
The SCIEX 7500 System was used to analyze a panel of pesticides from the Health Canada regulations for residues in Cannabis. Sub-ppb detection levels were easily achievable even with sample dilution and small volume injections, suggesting this platform is highly promising for the industry of residue testing in the routine laboratory.
The safety of tea is very important to human health due to the large rate of consumption around the world. Here, a LC-MS/MS rapid screening and detection method was established for the determination of pesticides in tea leaves using the SCIEX Triple Quad 3500 System. A QuEChERS method is used for sample pre-treatment providing high extraction recovery rate. This single injection provides high efficiency, high throughput and broad screening for the quantification of 222 pesticides in tea matrix.
Save time and minimize the risk of error. See how the advanced and flexible calculation capabilities in SCIEX OS Software can execute CCα and CCβ calculation automatically in the software, based on the CD657/2002/EC recommendation.
Poisoning incidents of animals due to mycotoxin in their feed has become frequent enough to warrant the creation of regulatory requirements for detection. Protecting animal health as well as the safety of the world’s food supply is critical. Here a complete method was developed for the detection of 30 mycotoxins in animal feed using the SCIEX Triple Quad 3500 system. Using optimized sample preparation, fast chromatographic run times and a single MS method with polarity switching, quantitative results were obtained that meets regulatory requirements.
Pyrethroids and macrocyclic lactones are insecticides widely used in the agriculture/horticulture industries and have been designed based on the naturally occurring family of pyrethrins. To monitor the levels of these insecticides in final food products, an robust and sensitive method is required. Here an assay has been optimized for the SCIEX Triple Quad 7500 system using a total run time of 17 mins, monitoring eleven different compounds. Excellent sensitivity in solvent was been demonstrated with LLOQ values down to 0.02 ng/mL. Detection levels of 5-10 ppb for most insecticides were also demonstrated in tea and spice.
Pesticide screening typically requires large numbers of compounds to be screened in a single method and these methods are routinely used to in food testing labs. In order to successfully detect and quantify large numbers of pesticides, time-scheduled methods with fast run times are required. Having quality separations with highly reproducible retention times is critical for success, to minimize time spent adjusting methods and reduce data loss. Here the reproducibility of the ExionLC 2.0 system for the LC-MS analysis of a large panel of 200 pesticides is assessed.
The SCIEX Triple Quad 7500 LC-MS/MS System - QTRAP Ready provides impressive levels of sensitivity, robustness and accuracy for trace level analysis of pesticide residues in food matrices. Here, over 1400 MRM transitions for 700 compounds were analyzed in a single analysis achieving quantification limits of 0.2 ng/mL for the majority of the pesticides tested.
A method was developed using SCIEX Triple Quad 3500 System to quantify 8 antibiotics in milk and was partially validated as per the regulatory guidelines described in 2002/657/EC directive recommendations. Local market milk samples were analyzed to check the presence of albendazole, fenbendazole, tylosin and tilmicosin.
