Residual Solvents

We use a gas chromatogrophy method to run analysis for residual solvents.

This is a state required test for all concetrate products, with the exception of CO2 production method.

We check for the following residual solvents:

  • butanes

  • heptanes

  • benzene 

  • toulene

  • hexane

  • Total xylenes (meta-eylenes, para-xylenes, or orthoxylenes)
