Conditions:

Room Temp: 298.15 $\pu{K}$
Pressure: 101.32 $\pu{kPa}$

Compiler:

C.L. Young

Methodology:

A conventional gas-liquid chromatographic unit fitted with a thermal conductivity detector was used. The carrier gas was helium. The value of Henry's law constant was calculated from the retention time. The value applies to very low partial pressures of gas and there may be a substantial difference from that measured at 1 atm. pressure. There is also considerable uncertainty in the value of Henry's constant since surface adsorption was not allowed for although its possible existence was noted.

Sample Information:
  1. L'Air Liquide sample, minimum purity 99.9 mole%.
  2. Touzart and Matignon or Serlabo sample, purity 99 mole%.
Measurement Errors:

Ambient temperature: $\delta T/\pu{K} = \pu{\pm 0.1}$ (estimated by the compiler)
Henry's Law Solubility Coefficient: $\delta H/\pu{atm} = \pu{\pm 6\%}$ (estimated by the compiler)
