Fully Automated QuEChERS Extraction and Cleanup of Organophosphate Pesticides in Orange Juice
A fully automated quick, easy, cheap, effective, rugged, and safe (QuEChERS) extraction and extract clean-up method is described for analysis of organophosphate pesticides in orange juice. This method uses GC–MS and LC–MS along with an industry standard robotic x,y,z-sampling system.
Consolidated GC-MS/MS Analysis of OCPs, PAHs, and PCBs in Environmental Samples
Analysis of OCPs, PAHs and PCBs in environmental samples through a consolidated GC-MS/MS method using the Thermo Scientific™ TRACE™ 1310 GC and the TSQ™ 8000 triple quadrupole GC-MS/MS.

Analysis of Pesticides in Citrus Oil Using PTV Backflush with GC–MS-MS Triple Quadrupole for High Sample Throughput
International regulations on maximum residue levels (MRLs) of pesticides in food cover hundreds of individual contaminants at the 10 ppb or below range. The analysis of citrus oil for pesticide contamination holds specific challenges.
Rapid Analysis of Pesticides in Difficult Matrices Using GC–MS–MS
Pesticides are widely used in agriculture to protect crops and to improve efficiency of production. Consequently, governments, food producers and food retailers have a duty to ensure that any residues occurring in foods for human consumption are at or below statutory maximum residue levels (MRLs). Regulation EC 396/2005 adopted in the European Union sets MRLs for more than 500 different pesticides in over 300 different food commodities.
