Recent regulations on food analysis require screening for pesticides using confirmatory techniques, such as GC-MS and LC-MS/MS. More than 1000 pesticides are used worldwide and, along with their metabolites and degradation products, are present in food. There is a demand for powerful and rapid analytical methods that can identify pesticides with high confidence in a broad range of food matrices and quantify at low concentrations with good accuracy and reproducibility. Challenges for pesticide residue laboratories at the moment are the request to test for more compounds, in a wider range of samples, all without sacrificing data quality. The QTRAP® 6500 LC-MS/MS system uses multi-component IonDrive™ technology to:
In addition, the QTRAP 6500 system uses the patented and proven Linear Accelerator™ trap technology to:
A new method for the quantitation and identification of hundreds of pesticides in food samples was developed and successfully applied to the analysis of complex food samples using the QTRAP 6500 system. Results are compared to QTRAP 5500 data. The increased sensitivity was used to extensively dilute sample extracts to eliminate ion suppression caused by matrix components and the extended linear dynamic range allowed quantifying more pesticides across a wider range of chemical properties. QTRAP scanning was used to investigate the presence of matrix components and to identify targets with high confidence through library searching. Quantitative and qualitative results were generated using MultiQuant™ and LibraryView™ Software.

The Echo® MS+ system is a novel platform for Acoustic Ejection Mass Spectrometry (AEMS) and combines the speed of acoustic sampling with the selectivity of mass spectrometry. This platform has been designed for high throughput analysis of small and large molecules. The technology combines Acoustic Droplet Ejection (ADE), an Open Port Interface (OPI) and could be coupled with the SCIEX Triple Quad 6500+ system or the ZenoTOF 7600 system.
The Echo® MS+ system comprises of an open-port interface (OPI) and acoustic droplet ejection (ADE) module which could be coupled with a mass spectrometer. The mass spectrometer could either be a SCIEX Triple Quad 6500+ system or the ZenoTOF 7600 system. This non-liquid chromatography based; high-throughput screening platform enables rapid analysis of compounds at speeds of up to 1 sample/second.
The ability to consistently achieve reproducible results on many complex samples across multiple days is critical to a routine clinical laboratory. Laboratories relying on analytical instrumentation require stability and robustness to perform a variety of screening and confirmatory assays with confidence. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) has become the preferred analytical method in the clinical laboratory to reliably perform clinical testing as it provides best-in-class performance and reliability for the most challenging assays. LC-MS/MS offers the required levels of sensitivity and specificity for the detection and quantitation of molecules from complex biological samples, helping laboratories deliver highly accurate data for a variety of clinically relevant analytes across a wide range of assays.
