Restek Oregon Pesticide Standard #4, 600 µg/mL, Acetonitrile, 1 mL/ampul

Oregon Cannabis Pesticide Standards meet the specific cannabis pesticide residue analysis needs of Oregon—and states with similar pesticide residue regulations/programs. Dissolved in acetonitrile and formulated for stability, the 59 compounds are separated into 6 x 1 mL solutions with individual analyte concentrations of 600 µg/mL—resulting in a convenient 100 µg/mL solution when blended immediately before use. Designed with quality and convenience in mind, this set of standards eliminates the need for in-house standards preparation. Restek’s Oregon Pesticide Standards are certified reference materials (CRM) manufactured and QC-tested in ISO-accredited labs.

*Reference materials containing chlorantraniliprole (500008-45-7) and daminozide (1596-84-5) must be sonicated for a minimum of 60 minutes prior to opening the ampul. Because each ultrasonic bath operates at a different energy level, 60 minutes is a guideline only. Longer sonication time will not affect product quality. These precautions apply to working solutions prepared in your laboratory as well. The amount of compound that precipitates depends on concentration and temperature. If you store your standards, even dilute solutions, at a temperature well below the label recommendation, allow extra sonication time.
