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)
