The preparation of accurate and stable OP standards is compli-
cated by their sensitivity to light, pH, heat, and water. Restek
has overcome these issues through our ongoing research into
OP pesticide mixtures to save your lab time and effort.
• Solvents are assayed to ensure low water content.
• Reference mixtures are stored in deactivated amber ampuls,
under an inert atmosphere.
• Purity is determined by a combination of methods: GC-FID,
HPLC, GC-ECD, GC-MS, LC-MS, refractive index, and
melting point.
