What instrument is used to detect the chlorine content in the gas phase?
Thread Content
There is a operating condition in which chlorine gas is introduced into the reactor; any chlorine gas that does not react goes to the absorption tower through the reactor’s vent. I need to monitor the chlorine concentration in the vent of the absorption tower to prevent chlorine from being released into the atmosphere. Do any experts have any recommendations for testing instruments?
It depends on the specific composition of the gases emitted. If optical instruments are used, the optical properties of the co-existing components must be taken into account. If a probe using wet chemical methods is used, interference from other components may need to be considered.

Focal Technology produces such devices that include lasers; we have only used their CEMS systems and laser meters. According to them, the international standards are all drafted by their company. You can get in touch with them to find out more
The content of background gas components needs to be taken into consideration; if there is no cross-interference, many analytical testing manufacturers can carry out the task.
It’s cost-effective to use an alarm. Having two should give a good effect. If the high concentration triggers an alarm for poisoning, recovery is too slow. If two are installed, they can be switched between for use.
