| Abstract: | The procedure for determination of volatile hydrocarbons concentrations in water and their partition constants using multiple equilibrium/he-adspace GC was investigated. The measured error increased linearly with r/KD. The effects of temperature, ionic strength, gas/liquid ratio on measured partition constants were discussed. |

| Keywords: | volatile hydrocarbon partition constant GC. |
