The QuEChERS method is a two-step process: extraction followed by clean-up. The extraction step
products use magnesium sulfate to aid extraction, along with either sodium chloride, sodium citrate,
or anhydrous sodium acetate for “base-sensitive” compounds (e.g., folpet or captan). The extraction step products are supplied in a 50mL polypropylene centrifuge tube for convenient extractions. The clean-up step products contain PSA (primary/secondary amine) for the removal of organic acids and polar pigments among other compounds. Some products couple the PSA with endcapped C18 for the removal of most lipids and sterols, or graphitized carbon black for the removal of sterols and pigments such as chlorophyll.
A variety of tube formats and bed weights are available to accommodate large and small sample sizes.
- Determine greater number of pesticides than with standard SPE
- Easy to use
- Available in a number of configurations
