QuEChERS Dispersive SPE Tubes – 150mg MgSO4, 25mg PSA, 2.5mg GCB (2mL, 100-Pack)

These pre-weighed QuEChERS dispersive solid-phase extraction (dSPE) tubes are designed for efficient sample cleanup in pesticide residue analysis and other analytical workflows. The optimized sorbent combination of Primary Secondary Amine (PSA), Magnesium Sulfate (MgSO4), and Graphitized Carbon Black (GCB) effectively removes matrix interferences including organic acids, excess water, pigments, and chlorophyll from complex sample extracts. Ideal for food safety testing, environmental analysis, and agricultural laboratories requiring consistent, reliable sample preparation.
