QuEChERS Kits and Standards

Easy-to-use QuEChERS kits enable fast sample preparation. Prepackaged dispersive and extraction kits, extraction salts, and ceramic homogenizers save time and are ideal for application areas such as food, pesticides, and mycotoxins. The QuEChERS (Quick, Easy, Cheap, Effective, Rugged, and Safe) dispersive solid phase extraction (dSPE) technique revolutionized multiresidue, multiclass pesticide analysis and can be performed in just three, simple steps.

The first step of QuEChERS is sample extraction using acetonitrile followed by a salting out step to remove water. Agilent offers buffered salts to accommodate various methods such as Association of Official Agricultural Chemists (AOAC) and European Standard (EN) as well as original (unbuffered) salts. QuEChERS extraction kits feature pre-weighed anhydrous salts in sealed packets to allow salts to be added after adding organic solvent to your sample – avoiding an exothermic reaction that can compromise analyte recovery. QuEChERS extraction kits can be purchased as salt packets only, salt packets with 50 mL extraction tubes, or salt packets with 50 mL extraction tubes and ceramic homogenizers. Ceramic homogenizers are effective in breaking up matrix and salt agglomerates for higher extraction recoveries of target analytes.

The second step of QuEChERS is sample clean-up. The extract from Step 1 is added to a dispersive solid phase extraction (dSPE) tube that is selected based on the specific method and matrix. Dispersive kits contain sorbents and salts and are supplied in 2mL or 15 mL centrifuge tubes to accommodate the aliquot volumes specified by current AOAC and EN methodologies. Choose from AOAC and EN dSPE kits targeted for a variety of matrices such as: general fruits and veggies, pigmented fruits and veggies, highly pigmented fruits and veggies, fruits and vegetables with fats and waxes, and many more. The Universal dispersive kits provide excellent recoveries and reproducibility for many types of fruits and vegetables.

In addition to AOAC and EN dSPE kits, the Bond Elut EMR-Lipid dispersive kit is an ideal choice for QuEChERS extracts that contain high percentages of fat or lipids. This innovative sorbent targets lipid removal while retaining analytes of interest. This yields higher sensitivity and more reproducible results, plus eliminates unwanted instrument downtime due to inefficient matrix removal. For more streamlined and automation-friendly lipid removal, be sure to check out Captiva EMR-Lipid cartridges and 96-well plates. The final step of QuEChERS is analysis usually via gas or liquid chromatography techniques.

Agilent offers chemical standards for commonly used regulatory methods, including the Association of Official Agricultural Chemists (AOAC) and the European Standard (EN) methods.

Agilent's Bond Elut PFAS WAX Named 2023 Top Product by Environment+Energy Leader

Agilent won a 2023 Environment+Energy Leader Award for Bond Elut PFAS WAX SPE Cartridges that improve efficiency in testing for PFAS substances, the so-called ‘forever chemicals.’ Bond Elut PFAS WAX enables scientists to confidently isolate PFAS from drinking water, wastewater, soil, sludge, tissues, and food. “The presence of PFAS chemicals in our daily lives is a grave concern,” the judges wrote, “making any technology that aids in their removal from the environment truly lifesaving.”

Per- and Polyfluoroalkyl Substances (PFAS) Analysis For Environmental Samples

Agilent offers complete end-to-end workflows for extraction, quantification even at Ultra-trace levels, and reporting of PFAS in the environment. This includes a range of sample preparation products, HPLC columns, chemical standards, PFC-free sample containment and other HPLC supplies, Ultra-high performance liquid chromatography (UHPLC) coupled to triple quadrupole mass spectrometry, e-methods, as well as gas chromatography products for sampling and analyzing a challenging range of trace-level volatile and semivolatile vapors of PFAS in air.

Full Workflow for US EPA Method 1633 for Targeted PFAS Analysis

Agilent announced a highly-anticipated, complete workflow solution for targeted per- and polyfluoroalkyl substances (PFAS) analysis using the United States (US) Environmental Protection Agency (EPA) Method 1633 (3rd draft). EPA Draft Method 1633 currently analyzes 40 PFAS compounds in wastewater and soil and is a complex and labor-intensive method, relying on multiple sample preparation and analysis steps. Success in running the technique depends on careful sample handling and the appropriate sample preparation supplies and instrumentation.
