Methodology:
(1) is partially partitioned into the vapor phase by equilibration of the aqueous sample with helium in a gas syringe, the vapor then being transferred to a gas sampling valve and then to a column of a gas chromatograp equipped with a flame ionization detector. By injecting gas samples from repeated equilibrations it is possible to calculate the amount of (1) in the original sample.

Measurement Errors:
Mass concentration (m/v) (1): ±10% (compiler)
System Components:
- Hexane, $\ce{ C6H14 }$; [110-54-3] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
Experimental Data
The authors reported the value of 16.2 mg(1)/dm-3 sln for the solubility of hexane in water. With the assumption of a solution density of 1.00 g cm-3, the corresponding mass percent, calculated by the compiler, is 0.00162 g(1)/100 g sln and the corresponding mole fraction, x1, is 3.4 × 10-6.
