   An aqueous solution with an excess of tribromomethane was stirred for 1 day before being introduced into a 1 liter glass vessel. Nitrogen entered at the bottom of the vessel through a sintered glass disk. The exit gas flow rate was measured by a soap bubble flow meter. The  concentration of tribromomethane in water was determined by gas chromatography. The GC was equipped with both dual flame ionization detector and an electron capture detector.
