Does anyone know any company that makes custom liq. mixes. Basically I need in a solution, 1-alkene mix from C7-C12. I need about 25 ml of this in high concentrations of the fuels. Like, 10,000 mg/L.

I usually try Accustandard or Chemservice if I want a custom standard, but I'll try o2si in a pinch.
