| Summary: | The effect of inlet radius of a transmission type
optical gas cell on its response time is reported. Six gas
cells of varying lengths, and internal radius of 0.32cm were
considered at first and then other internal diameters were
also investigated afterwards. The effect of inlet radius is
easily discernible at all velocities considered; however it is
more pronounced at lower flow rates. At a velocity of
16.79cm/s of ozone gas, and for a target sensing time of ≤
0.5 seconds; we observed that the inlet radius
requirements for gas cells of varying lengths and varying
internal diameters is not the same for a specific target
sensing speed. The length and the internal radius of a gas
cell are proportional to its inlet radius |
