An Improved QuEChERS Method for UPLC-MS/MS Determination of Multiresidue Mycotoxins in Grains

22 Dec 2015

Mycotoxins are toxic compounds produced by molds or other fungi that can grow on foodstuffs intended for domestic animal or human consumption. Ingestion of food containing part-per-billion concentrations of some mycotoxins may cause severe illness. In this poster, an evaluation of the QuEChERS method is presented for the determination of mycotoxins in whole grain wheat, maize and rice flours.

ACQUITY UPLC® BEH C18 and C8 Columns

Waters

ACQUITY UPLC® BEH C18 and C8 columns were designed to be the universal columns of choice for most UPLC® separations by providing the widest pH range.They incorporate trifunctional ligand bonding chemistries which produce superior low pH stability and ultra-low column bleed. This low pH stability is combined with the high pH stability of the 1.7 µm BEH particle to deliver the widest usable pH operating range. In addition, these new chemistries also utilize new, proprietary endcapping processes which produce outstanding peak shape for bases. These bonding chemistries and particle synthesis innovations produce the sharpest peaks, highest efficiencies and maximum MS sensitivities.

UHPLC and HPLCHigh performance liquid chromatography (HPLC) and ultra high performance liquid chromatography (UHPLC), also known as UPLC, are analytical techniques used to separate, identify and quantitate components of complex mixtures including biological samples such as proteins and lipids as well as chemical mixtures of pesticides, drugs and oils. Both techniques are liquid chromatographic methods but differ by operating pressures (HPLC < 6000 psi < UHPLC ). Components of HPLC and UHPLC systems include columns, detectors, pumps, autosamplers and column heaters. Explore a range of UHPLC and HPLC columns for your specific sample needs including reverse phase, normal phase, ion exchange, HILIC, ion exclusion and size exclusion columns. For more specialized HPLC, explore FPLC, countercurrent LC and simulated moving bed systems. Find the best UHPLC and HPLC equipment in our peer reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.LC-MSLC-MS (liquid chromatography-mass spectrometry) systems and equipment are used for separation and quantitative analysis of complex mixtures, combining liquid chromatography and mass spectrometry. Quantify proteins, contaminants, pesticides or screen for drug metabolites with a high level of sensitivity. LC-MS systems and equipment include reverse phase, normal phase and specialized columns integrated with various MS detectors such as time-of-flight (TOF), quadrupole, orbitrap or ion trap mass analyzers. LC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzer give greater sensitivity and resolving power to your analysis. Find the best LC-MS equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Environmental Monitoring and TestingEnvironmental monitoring and testing uses handheld portable analyzers, kits, spectrometers or chromatography systems for air, water, soil, food and other sample testing. Useful features of analyzers such as BOD and COD include portability, easy calibration, automation and sensitivity.  Environmental test kits for pH, water, moisture, etc, should be accurate, sensitive, reliable, fast and easy to use.Food and Beverage AnalyzersFood and Beverage Analyzers are commonly used to provide information about the chemical composition, structure and physical properties of food materials.Food and Beverage ProcessingFood and Beverage Processing involves the preparation of food products for further analysis. Typical instrumentation includes blanchers, color sorters, cookers, grinders, and refrigeration. These are used to replicate the processes commonly used in the commercial preparation of food and beverages.QuEChERSThe QuEChERS (Quick, Easy, Cheap, Effective, Rugged, and Safe) method is a streamlined approach that is used to extract multi-residue target compounds from food samples. It is most commonly used by analytical chemists studying pesticide residues in food.AgricultureAgriculture research focuses on improving food production, crop management, and sustainability. This includes plant breeding, pest control, and soil health studies. Explore agriculture research tools in our peer-reviewed product directory; compare products, check reviews, and get pricing directly from manufacturers.Food SafetyFood safety describes the prevention of food-borne illnesses. Contamination with a variety of pathogens can be prevented with adequate temperature control, hygiene and labeling. Food samples can be tested using GC/MS, HPLC, SPE, and qPCR to ensure their adherence to regulations.MycotoxinsToxic chemicals such as Aflatoxin and Alkaloids that are produced by fungi are known as mycotoxins. In humid conditions, fungi can proliferate and colonize on crops to levels that can be damaging to human health. Food TestingFood testing refers to a variety experiments including PCR, mass spectrometry, processing, QuEChERS, analyzing and Kjeldahl.
