Agilent Dispersive SPE 15ml, Pigment Sample AOAC 5982-5258

The Agilent Dispersive SPE 15 mL Pigment Sample (catalog 5982-5258) is a QuEChERS dispersive cleanup kit supplied in 15 mL centrifuge tubes and designed for AOAC QuEChERS workflows. It is formulated for pigmented fruits and vegetables to remove pigments and other matrix interferences from sample extracts prior to multi-residue pesticide analysis. Each tube contains a defined mix of sorbents and drying salt to clean an aliquot of extract according to the AOAC procedure.

Key Features:

• Tube size/volume: 15 mL
• Kit contents per tube: 400 mg PSA, 400 mg GCB, 1200 mg MgSO4
• QuEChERS sample type: Pigmented fruits and vegetables
• SPE/Agency methods: SPE method AOAC 2007.01; Agency method AOAC 2007.10
• Format: Dispersive SPE in centrifuge tubes (for aliquot cleanup)

Advantages:

• GCB and PSA sorbents specifically target pigments and polar matrix interferents (e.g., carotenoids, chlorophyll, polar organic acids).
• MgSO4 drying salt removes excess water and improves analyte partitioning for cleaner extracts.
• Prepares extracts compatible with AOAC QuEChERS multi-residue pesticide workflows, helping reduce matrix effects.
• Packaged in 15 mL tubes sized for the aliquot volumes specified by AOAC methods, simplifying sample cleanup steps.
