QUICK AND EASY LAB SAMPLE PREP FOR GCMSMS AND LCMSMS MULTIRESIDUE PESTICIDE ANALYSIS

is the new brand that identifies the “QuEChERS Products” made in Italy for the extraction and clean up of analytes from a wide variety of matrices such as fruits, ve-getables, meat products, fruit juices, wine, spices, cereals, ho-ney, dried fruit. By means of this treatment one can detect analytes as pesticides, mycotoxins, veterinary drugs, acryla-mides, antibiotics, polycyclic aromatic hydrocarbons, etc.The method based on a paper published in 2003 by the US Department of Agriculture - Eastern Regional Research Center - in Wyndmoor, PA (M. Anastassiades, S.J. Lehotay, D. Stajnbaher, F.J. Schenck) admirably replaces old extraction methods drastically reducing execution and costs arising from: solvents, glassware and special laboratory equipment.Method “Original” of 2003 has been joined by the methods AOAC 2007.01 and EN 15662 approved by European and American Food Regulatory Agencies that are surely the most used and disseminated.

PROCEDURE INVOLVING TWO PHASES

Deriving from the first step, the organic phase (acetonitrile extract) comes in contact with other typical clean up sorbents: pri-mary and secondary amine (PSA), graphitized carbon black (GCB) or C18 with the purpose of removing sugars, lipids, sterols, organic acids, proteins, carotenoids, chlorophyll and other pigments in addition to the residual water by the use of magnesium sulfate. After that it follows shaking and centrifugation. The anhydrous acetonitrile phase is ready for analysis in GCMS / MS directly (LVI) or after exchange of solvent, while the injection LCMS / MS is ready after sample dilution with mobile phase.

The analytes are extracted from the matrix by the use of acetonitrile and different types of salts and buffers. After the partition liquid-liquid (LLE) it follows: shaking, centrifugation and collection of acetonitrile phase.

DISPERSIVE SOLID PHASE (d-SPE)

EXTRACTION (LLE)

PRODUCTS WITH LOW WATER CONTENTThe extraction QuEChERS is designed primarily for food products with a high water content but it also applies to dried foods by adding during comminution step, weighted amount of water depending on the type of sample as defined in the CEN Guidelines.

WHAT IS ?

PRODUCTS

The line of products branded is the most completed line on the market. It was realized in every possible variant of packaging “Ready to Use” (conical tubes, self-standing tubes, packets, etc.) and in different wording so as to satisfy all the official methods (EN 15662, AOAC 2007.01, etc.). The raw materials are selected and analyzed for each batch in the laboratory accredited to ISO / IEC 17025: 2005. Each batch of Falcon tubes, test tubes and caps are subjected to checks as leak and release tests.Each production lot of the is accompanied by a certificate of analysis showing the traceability of components and traceability of the analytical data as well as a safety data sheet complies with the REACH Reg. (EC) 1907/2006.

CHOOSING A dSPE SORBENT

PSA is the base sorbent used for QuEChERS clean-up (dSPE tube) because removes substances

that might act as instrumental interferences.

In addition to PSA, C18 removes lipids and non polar interferences.

REMOVEsugar, fatty acids, organic acids,

anthocyanine pigments

REMOVElipids, non polar interferences

REMOVEpigments, sterols, non polar interferences

PSAPrimary and secondary amine

C18Octadecyl

GCBGraphitized carbon black

GCB removes pigments that can degrade GCMS performance but EN15662 recommends less GCB because can have a negative ef-fect on the recoveries of certain pesticides like : Chlorothalonil, Per-methrin, Deltamethrin, Coumaphos ,Thiabendazole, Quintozene, etc.

Further Information: Additional information useful to the analyst planning QuEChERS analysis may be found to the following website:

For each type of matrix you can choose the most appropriate d-SPE. Tubes d-SPE with MgSO4 and PSA effectively remove polar organic acids, sugars, anthocyanine, lipids and sterols. Some fruits and vegetables (spinach, red peppers, carrots, etc.) with a high content of non-polar pigments such as carotenoids, chlorophyll, etc. require d-SPE with graphitized carbon black (GCB) for the discoloration. The elimination of pigments is necessary to avoid accumulations in the liners of GC’s injector.
