Pesticide Internal Standards

Pesticide internal standards are reference solutions added to samples and calibrators in pesticide residue analysis by GC or LC. Food, water and agricultural testing laboratories use them to compensate for extraction losses and instrument drift across a batch.

Reagecon supplies both products listed here: a single compound internal standard, Decafluorobiphenyl at 1000 µg/mL in acetonitrile, and a four compound pesticide internal standard mix in methanol prepared for the HJ827 water test method. They sit next to the main Pesticide Standards range under Organics.

Pick the single compound standard as a general purpose marker, or the multi-compound mix when a specific water analysis method calls for several reference compounds at once. Solvent choice should follow your sample preparation scheme. Lancetech Limited welcomes quotation requests for other pesticide internal standards.
