Restek Canadian Pesticide Standard #3, 100 µg/mL, Acetonitrile, 1 mL/ampul

*This reference material contains pyrethrins, a technical mixture that is composed of six active insecticidal compounds. The ratio of each of the six compounds in this specific mixture is provided in the order they have eluted under the run conditions listed on the certificate. Only the peak corresponding to the pyrethrin compound with the highest signal intensity is labeled on the chromatogram. Due to the nature of pyrethrins, lot-to-lot variation in composition and purity may be observed based on raw material source.

**This reference material contains both the Spinetoram J and L isomers (187166-40-1 and 187166-15-0); however, CAS# 935545-74-7 is displayed on the certificate as this is the neat material dissolved in the solution. CAS# 935545-74-7 is a blend of Spinetoram J and L, and the ratio of each material isomer is displayed on your certificate of analysis.

†This reference material contains Spinosad A and D isomers (131929-60-7 and 131929-63-0); however, CAS# 168316-95-8 is displayed on the certificate as this is the neat material dissolved in the solution. CAS# 168316-95-8 is a blend of Spinosad A and D, and the ratio of each material isomer is displayed on your certificate of analysis.
