The preparation of accurate and stable OP standards is compli-
cated by their sensitivity to light, pH, heat, and water. Restek has
spent more than four years researching OP pesticide mixtures.
Our research results:
• OP standards have a maximum of 12 months shelf life due to
their volatility. It is our policy to ship standards with no less
than 3 months shelf life remaining.
• Solvents are assayed to ensure low water content.
• Reference mixtures are stored in deactivated amber ampules,
under an inert atmosphere.
• Purity is determined by a combination of methods: GC/FID,
GC/FPD, GC/NPD, DSC, and HPLC/UV.
