Application of Online Dissolved Oxygen and Gas Phase Oxygen Analysis Monitoring Technology in Injection
The online dissolved oxygen measurement system and the gas phase oxygen analysis measurement system can reduce the free oxygen and residual oxygen of physic liquor during the injection production process.In the actual production,the online dissolved oxygen measurement system and gas phase oxygen analysis measurement system are installed in the injection preparation and potting process to carry out online monitoring and data collection,and the process monitoring is effective and the product quality is stable.Through the monitoring of the online dissolved oxygen and gas phase oxygen analysis measurement system,the dissolved oxygen content in the physic liquor can be controlled below 500 μg/L,and the residual oxygen in the bottle can be controlled below 2％,which can effectively reduce the oxygen content in the injection products,solve the problem of product discoloration and related substances exceeded due to oxidation decomposition,so as to improve product quality.
