Q-sep™ QuEChERS Tubes for Pesticide Residue Analysis • Fast, simple sample extraction and cleanup using dSPE. • Fourfold increases in sample throughput. • Fourfold decreases in material cost. • Convenient, ready to use centrifuge tubes with ultra pure, preweighed adsorbent mixes. Quick, Easy, Cheap, Effective, Rugged, and Safe, the QuEChERS ("catchers") method, developed by the USDA Eastern Regional Research Center, has becom…

The mixer mill MM 400 is a compact versatile bench-top unit, which has been developed specially for dry, wet and cryogenic grinding of small amounts of sample.

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The process of fat determination in food and feed matrices is a routine analysis still relies on outdated and matrix-dependent methods which use obsolete and time-consuming technologies.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…

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

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 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…

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.

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…

Dispersive SPE (dSPE), often referred to as the "QuEChERS" method (Quick, Easy, Cheap, Effective, Rugged, and Safe), is modern sample prep technique that is becoming increasingly popular in the area of multi-residue pesticide analysis in food and agricultural products.  Using the QuEChERS method, food/agricultural samples are first extracted with an aqueous miscible solvent (e.g., acetonitrile) in the presence of high amoun…
