Signal suppression, elevated baselines, and inconsistent quantification are the predictable outcomes of inadequate cleanup. Chlorophyll is particularly destructive in GC: it's non-volatile and thermally unstable. Residues accumulate in inlets and columns, creating active sites that degrade analytes, distort peak shapes, and shorten column life. If you're analysing pesticides in high-chlorophyll matrices without proper pigment removal, you're burning through columns and compromising data. ![600 x 308 CD Blog UCT - Pesticide Testing](https://blog.chromatographydirect.com/hs-fs/hubfs/Canva%20images/600%20x%20308%20CD%20Blog%20UCT%20-%20Pesticide%20Testing.png?width=600&height=310&name=600%20x%20308%20CD%20Blog%20UCT%20-%20Pesticide%20Testing.png) ## Why Not Graphitized Carbon Black? GCB has been the default for pigment removal in QuEChERS workflows. It removes chlorophyll effectively. The problem: GCB also retains planar pesticides. Compounds like chlorothalonil, hexachlorobenzene, and other flat-structured molecules show poor recoveries because GCB can't distinguish between planar pigments and planar analytes. You lose the compounds you're trying to measure. ## ChloroFiltr®: The Fix UCT's ChloroFiltr® is a polymer-based sorbent designed specifically to eliminate chlorophyll from QuEChERS acetonitrile extracts **without compromising planar pesticide recoveries**. It targets pigments selectively, leaving your analytes intact. It's been validated across studies analysing hundreds of pesticides in high-chlorophyll matrices, consistently delivering: - **Complete chlorophyll removal** - **Reliable recovery of planar and non-planar pesticides** - **Cleaner extracts that protect instrument hardware** ## Available Formats - **dSPE** (dispersive solid-phase extraction tubes) - **Push-through cartridges** - **SpinFiltr®** centrifuge devices Pick the format that fits your workflow. Same sorbent chemistry, different throughput options. ## Why Chromatography Direct The home of chromatography consumables. We stock UCT's full ChloroFiltr® range across all formats, plus the complementary QuEChERS salts and cleanup sorbents you need for complete pesticide residue workflows. High-quality consumables at unrivalled prices, making your lab budget go further. We're so much more than chromatography. Pesticide residue testing, food safety, agricultural monitoring: if your lab needs reliable sample prep for complex matrices, we supply it. Specialists who understand the chemistry, not generalists selling from a catalogue. Talk to us about method-specific bundles and bulk pricing. --- **References** 1.
