Methodology:
The saturation vessel is drawn in the original paper. (2) was saturated with (1) via the vapor phase: a few drops of (1) were put on the bottom of a tight-fitting flask containing a small flask filled with water. Complete saturation was reached by shaking overnight in an upright position. Samples were taken from the aqueous solution with a microsyringe through the septum and injected into the gas chromatograph equipped with a flame ionization detector. The gas chromatographic conditions are described in the paper.
Sample Information:
- Fluka purum.
- Tap-water was refluxed for eight hours in the presence of $\ce{KMnO4}$ and $\ce{KOH}$ and distilled. The whole process was repeated once more.
Measurement Errors:
Mass concentration (m/v) (1): error given above (standard deviation)
System Components:
- Octane, $\ce{ C8H18 }$; [111-65-9] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
