Remove the Pigments Without Losing the Pesticides

Pigments can interfere with chromatographic separation and MS detection. Graphitized carbon black (GCB) is widely used during sample preparation to remove color from tomatoes, berries, coffee, and other highly pigmented food and environmental samples. However, using GCB for matrix cleanup can reduce recovery and reproducibility for sensitive targets such as planar pesticides.

Agilent Carbon S sample preparation products demonstrate superior results compared to GCB. They offer excellent removal of pigments and improved recoveries especially for planar pesticides with a simplified workflow.

Why Agilent Carbon S sorbent?

  • Agilent Carbon S sorbent is an advanced hybrid carbon material with optimized carbon content and pore structure.
  • Significant improvement on sensitive pesticides recovery and reproducibility.
  • Decent pigment removal, comparable to GCB sorbent and better than other sorbents for pigment removal.
  • Improved sorbent selectivity and thus better balance.

A Simplified Workflow

A simple and reliable sample preparation method is critical to your ability to detect trace amounts of analytes in complex food and environmental matrices. You can speed up your workflow and improve your detection of target analytes particularly planar pesticides with Agilent Carbon S.

More reproducible results for pesticide analysis

The Carbon S sorbent improves your overall passing rate for multiclass multiresidue pesticide analysis over the traditional GCB sorbent—with improved recoveries and RSDs of planar pesticides. That adds up to better recoveries and RSDs.

Simplify your sample preparation workflow

To improve planar pesticide recoveries with traditional GCB, the addition of toluene is commonly used. The extra steps increase cleanup time, and introduce a toxic solvent to your process. Carbon S sample preparation products give you all the advantages of greater pesticide recovery without the need for toluene. And that enables single-step LC and GC sample preparation (with a final drying step for GC).

With their optimized carbon content and pore structure, Agilent Carbon S sample preparation products reliably remove coloring from the most challenging pigmented matrices.
