Patent GB-463384-A (GB)
Title: Improvements in gas analyzers
IPC: G01N7/04
Filed: 1936-09-18
Abstract: A gas analysis apparatus comprises a pivotally mounted casing containing a liquid absorbent reagent, in which a gas measuring chamber is mounted, means for supplying gas to the measuring chamber and then conducting it to the casing, and means, e.g. a non-absorbent liquid such as mercury, which automatically closes the gas supply and forces the gas in the measuring chamber through the absorbent liquid in the casing when the whole device <PICT:0463384/III/1> <PICT:0463384/III/2> is moved to another angular position, the amount of gas absorbed then being measured.  Fig. 3 shows the casing 10 in its normal or sampling position on pivot 31.  The upper portion is filled with steel wool or the like 50 moistened with the absorbent, such as caustic potash, and the chamber 19 is filled with mercury to the level 45, thus filling tube 43 with mercury nearly to its junction with the gas measuring chamber 20.  Gas is supplied through tube 35 and then passes through tube 37, chamber 20, and tubes 42, and 40 out to the atmosphere, since the byepass tube 38 is sealed in trough 32.  Tube 39 leading into the casing has a capillary bore so that during sampling, substantially no gas passes into the casing 10. The gas is passed until all previous samples are expelled, and the casing is then pivoted to the position shown in Fig. 4.  The mercury in chamber 19 passes into chamber 20 via pipe 43 to expel the gas therein and seal tube 37.  Also, the mercury in trough 32 seals the byepass tube 40 and opens tube 38, so that the gas supply need not be interrupted during analysis.  The sample in chamber 20 is forced through tubes 42 and 39 into the steel wool whereby carbon dioxide, sulphur dioxide or other constituent is absorbed, and the absorption measured on gauge 56. The apparatus is then returned to the position shown in Fig. 3, for further analyses to be made.  The temperature of the gas is brought to the temperature of the absorbent by its passage through tubes 35 and 37, and chamber 20, which are surrounded by the liquid.  Any liquid rising in tube 39 owing to reduction in pressure is discharged through the byepass tube 40 so that the walls of tubes &c. through which the gas is passed during sampling are not wetted by the reagent.  Any such excess of liquid is drained out of trough 32 by a suitable wick.  In the modification shown in Fig. 6, part of the tube 37 passes outside the casing so that the absorption is measured by the respective mercury levels in tubes 42 and 37 in conjunction with a suitable scale and pointer 65 and 66. the tube 37 being open to the atmosphere during the absorption cycle.
