The industrial standard for food sample preparation

The process of fat determination in food and feed matrices is a routine analysis still relies on outdated and matrix-dependent methods which use obsolete and time-consuming technologies. The ETHOS X offers a new approach to gravimetric fat determination, moving toward a more modern, greener and more efficient approach to total fat, Fatty Acid Methyl Ester (FAME) and free fat determinations in food and feed matrices.

The latest addition to UCT’s QuEChERS line puts a new “spin” on dSPE. SpinFiltr™ combines the practice of conventional dSPE with the added benefit of ultrafiltration. UCT’s new format of dSPE salts paired with a 0.2µm filtration device, simultaneously removes unwanted matrix compounds and filters samples without the need for any additional steps. With traditional dSPE, analysts must pay close attention when removing t…

Quick, Easy, Cheap, Effective, Rugged for multiresidue pesticide clean-up

Unlike other suppliers of QuEChERS extraction kits, Agilent QuEChERs salts and buffers are pre-packaged in anhydrous packages. This allows you to add them after adding your solvent to the sample, as specified in the QuEChERS methodologies. Extraction Kits include: 50 quantity of 50 mL polypropylene centrifuge tubes with caps MgSO4 and NaCl, or other salts for buffering; pre-weighed in anhydrous packet

QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) is a sample extraction and clean-up technique used for the analysis of multiple pesticide residues in agricultural products. UCT manufactures a wide variety of pre-filled tubes and reagent pouches for all QuEChERS method variations including PSA, C18, buffers, anh. MgSO4, NaCl, ChloroFiltr, and carbon.

Agilent offers dispersive SPE kits that are specifically designed to remove lipids from high-fat samples, though they can be used with any sample type. The sorbent will pull interfering lipids from samples while leaving analytes behind. The final polishing step removes excess water and improves analyte partitioning. These kits contain 1 g of preweighted sorbent in 15 mL centrifuge tubes. They can easily accommodate the aliquot…

“QuEChERS” (Quick, Easy, Cheap, Effective, Rugged, and Safe) - Supel™ QuEPSA/C18 Tube, pack of 100, suitable for 2007.01 per AOACDispersive SPE (dSPE), often referred to as the "QuEChERS" method, is an emerging sample prep technique that is becoming increasingly popular in the area of multi-residue pesticide analysis in food and agricultural products. In dSPE, food/agricultural samples are first extracted with aqueous miscibl…

QuEChERS Dispersive SPE methods offer a convenient and effective approach for extraction and clean-

Designed for use in all QuEChERS methods for pesticides in fruits and vegetables, including the original unbuffered method, AOAC 2007.1, and EN15662. Kit contains organochlorine, organonitrogen, organophosphorus, and carbamate fungicides and insecticides commonly used on fruits and vegetables. Volatile, polar, active, base-sensitive, and nonvolatile compounds are included to allow comprehensive evaluation of QuEChERS extracti…

DisQuE Dispersive Sample Preparation used for QUECHERS Method AOAC Method 2007.01. The kit consists of 100 units each of salt pouches, empty 50mL centrifuge tubes and clean-up tubes. Each DisQuE pouch contains 6 grams of magnesium sulphate and 1.5 grams of sodium acetate. Each 2 mL DisQuE Clean-Up tube contains 150 mg of magnesium sulphate and 50 mg PSA (primary-secondary amine SPE sorbent)

The QuEChERS Clean-up step is rapidly completed using the QuICK QuEChERS cartridge. This self-contained cartridge contains 110 mg of anhydrous MgSO4 and 180 mg of PSA. Placed on the end of a disposable syringe, the QuEChERS extract is pushed through directly into a sample vial for analysis. Clean-up is equivalent to dSPE clean-up, but faster and easier, eliminating the need for centrifugation.

Chlorophyll in QuEChERS extracts must be removed to reduce potential instrument downtime. This is removed from extracts using graphitized carbon black (GCB) Unfortunately, GCB also removes planar analytes reducing analytical accuracy. ChloroFiltr®, used in place of GCB in dSPE tubes, removes unwanted chlorophyll without removing pesticides or environmental analytes. No change in procedure are required.

Targeted lipid removal from fruit, vegetable, and agricultural based sample types.

Build Outstanding Analytical Performance on a Strong Foundation of Sample Prep

Agilent offers dispersive kits with sorbents and salts supplied in 2 or 15 mL centrifuge tubes to accommodate the aliquot volumes specified by current AOAC and EN methodologies.

There is a growing need for applications in food and environmental areas able to cope with the analysis of a large number of analytes in very complex matrices. New analytical procedures demand sensitivity, robustness, effectiveness and high resolution with reduced analysis time. To improve the efficiency of traditional methods, a new sample preparation approach was developed. It’s called QuEChERS and it says it all: an acrony…
