A novel electrochemical analyser for hydrogen determination in aluminium melts

摘要

The results achieved during the field trials show that the novel electrochemical hydrogen analyser s capable of performing quantitative in-situ measurements of hydrogen in aluminium melts under industrial conditions. Readings were reproducible and could be taken a few minutes after immersing the probe. It would appear that the analyser might have read slightly too low, the reasons for this are currently being investigated. The most extensively tested probe survived numerous dips and an overall dwell time in the melt of around 20h.Particular advantages of the new analyser are ease of fabrication and simple application, as well as on-line use and fast response. Successful field trials demonstrated the potential of the device for industrial application.
