The paper presents basic information on the preparation of environmental samples for trace analysis. Sample preparation is of utmost importance for the quality of analytical results and their usefulness for decision making in the area of environmental protection and management. The type and number of operations required for a given procedure is determined by the available information about the ...
متن کاملMethod development for simultaneous determination of 41 pesticides in rice using LC-MS/MS technique and its application for the analysis of 60 rice samples collected from Tehran market
For the first time, a multi-residue methodfor simultaneous determination of 41LC-amenable pesticides in rice, belonging to different chemical classes has been developed in Iran by LC-MS/MS. The pesticides were analyzed simultaneously in a single run using positive electrospray ionization with multiple reaction monitoring (MRM) after extraction with slightly modified QuEChERS method. The calibra...

متن کاملAutomated Derivatization, SPE Cleanup and LC/MS/MS Determination of Glyphosate and Other Polar Pesticides
Glyphosate and glufosinate are widely used herbicides and, thus, there is an interest in the reliable and sensitive determination of glyphosate in water and food. These pesticides are diffi cult to extract and analyze because of their high polarity. In this report, we describe an automated workfl ow for the FMOC-derivatization, sample cleanup, and LC/MS/MS analysis using a GERSTEL MultiPurpose ...
