    摘要: In a method of determining amounts of condensable species present in a gas containing condensable species a probe is placed into a gas containing condensable species. The probe has a plurality of spaced apart contacts on an outer non-conductive surface. That surface is heated at a selected heating rate and then cooled at a selected cooling rate over a selected time period. During that time period current flow between the contacts and the temperature of the non-conductive surface is monitored over the selected time period. Peaks in a plot of the current flow over the selected time period and the temperature for the time corresponding to each peak are then correlated to the condensable species has a kinetic dew point at each identified temperature. The identified temperature for each identified species is compared to a predetermined correlation of dew point temperature and concentration for that species to determine the concentration of that condensable species present in the gas.

    摘要: A metal or metal compound (10) able to trap a sulfur component in exhaust gas is arranged in a flow passage of exhaust gas in an internal combustion engine. When the amount of sulfur component trapped in the metal or metal compound (10) increases over the passage of time, a property of the metal or metal compound (10) which changes along with the increase in the amount of trapped sulfur component is measured and the sulfur component in the gas is detected from the measured property.

    摘要: A sulfur dioxide detector embodying an SO₂-oxidant bioagent comprises a bio-membrane (40) located at one end of an oxygen concentration sensor (2), the bio-membrane (40) consisting of the bioagent (e.g. Thiobacillus thiooxidons, Thiobacillus ferroxidons or an enzyme devided from such a microorganism) provided between an immobilized membrane (41a) and a gas permeable membrane (41b). The sensor (2) has an electrode (60) in contact with the immobilized membrane (41a) of the bio-membrane (40). A dish-shaped cell (32) has an open end which is in contact with the gas permeable membrane (41b) so that sulfurous acid in an SO₂-containing solution supplied to the cell (32) during use is oxidized to sulfuric acid so as to change the output from the sensor (2). An inlet hole (33) and an outlet hole (34) are formed on a sidewall of the cell (32) with the outlet hole (34) located directly above the inlet hole (33) so that foam produced during use, when the SO₂-containing solution is supplied to the dish-shaped cell (32) through the inlet hole (33), can be drained from the outlet hole (34).
