New Reference Materials
✔ High concentration mix.
✔ Includes all US EPA Method 8270 organophosphorus pesticide (OPP) target compounds.
✔ Enhanced stability—prepared in methanol-free methylene chloride.
By Katia May, Ph.D., R&D Chemist
This new mix complements our 8270 MegaMix™ (cat.#31686), Appendix IX Mix #1 (cat.#31625), and
Appendix IX Mix #2 (cat.#31806), which do not include OPPs.

Carbon Number Distribution Marker Standard
For Texas Method 1005 Rev. 03 and Method 1006
✔ Includes the minimum required aliphatic markers defining the
carbon ranges of interest.
✔ Completes set of reference materials for TNRCC methods 1005 and 1006.*
Organophosphorus Pesticides Mix
TNRCC Method 1006 is used for determining the total petroleum hydrocarbon (TPH) mass within boiling point
ranges of aliphatic fractions (C6-C35).
European Pharmacopoeia/ICH Class 1 Mix
✔ Concentrations revised to the latest standards for EP Class 1 residual solvents.
✔ Dimethylsulfoxide:water solvent for better dispersion during preparation.
European Pharmacopoeia (EP) monographs now have legal status in 26 member countries. International
Conference on Harmonization (ICH) guidelines for residual solvents are an international standard and have
been adopted by the United States Pharmacopoeia. The revised concentrations for the components in European
Pharmacopoeia/ICH Class 1 Mix meet the latest EP standards. We also offer EP/ICH Class 2 mixes of solvents
that pose lesser health hazard (cat.#36229, cat.#36230, cat.#36231). Stabilwax® (cat.#10640) and Rtx®-1301
(G43) (cat.#16085) capillary columns are ideal for analyses of residual solvents.
