 instrument for laboratory qualification of gas evolution rates from chemical processes and decompositions.


  • Permits laboratory quantification of gas evolution rates from chemical processes
  • Very simple to use
  • May be connected to a Mettler RC1 set-up or to any other data acquisition system 
  • Volumetric measurement does not require composition of gas to be known
  • Suitable for a wide range of hazardous gases with inert construction materials

                                          Above: Gas Burette apparatus                 Current design with U-tube mounting board

The principle of the apparatus is very simple. Gas generated by a process displaces the fluid in the U-Tube and causes a pressure increase (directly equivalent to the volume of gas evolved). The pressure increase (measured as the head of a column of liquid in the U-Tube) is recorded by a sensitive transducer mounted on the side of the U-tube. Once the pressure reaches a pre-determined limit selected and calibrated by the operator, a solenoid valve opens and relieves the pressure by venting the gases.

The pressure measured by the transducer, and the number times the solenoid valve has activated, are recorded by link-up to a data acquisition system thus enabling the total gas evolved from the process to be calculated.
