Abstract
The release of gas from a solution is monitored by means of a microphone responsive to the sound due to the gas bubbles breaking through the surface of the liquid. The liquid is confined within a suitable closed vessel, the microphone being supported above the liquid facing the surface. The microphone output is amplified in a conventional audio amplifier and applied to operate a recording and, if desired, signalling device. The Specification gives detailed measurements of the sound levels associated with the release of a number of gases. It is shown that not only the commencement and termination of gas release, but also changes in the rate of gas release may be detected.ALSO:The release of gas from a solution is monitored by means of a microphone responsive to the sound due to the gas bubbles breaking through the surface of the liquid. The liquid is confined within a suitable closed vessel, the microphone being supported above the liquid facing the surface. The microphone output is amplified in a conventional audio amplifier and applied to operate a recording and, if desired, signalling device. The Specification gives detailed measurements of the sound levels associated with the release of a number of gases. It is shown that not only the commencement and termination of gas release, but also changes in the rate of gas release may be detected. One example relates to the release of nitrogen, the invention being applied to detect the point at which a significant rate of decomposition occurs in a solution of diazo compounds. The microphone output may serve to operate a warning device or may control automatically a pH regulator for the addition of acid or alkali to stabilize the solution.
