Tighter process control in acid pickling baths
Online ion chromatography from Metrohm has enabled tighter process control of acid pickling baths, as the final cleaning stage prior to metal plating
These include lengthy times for pH equilibration (sometimes as long as 5 minutes), diaphragm blockages due to silver chloride leaching out of the electrode, or the necessity to add a salt to the water in order to speed up response times (this can affect the original pH).
Metrohm have recently launched the NEW Aquatrode plus, designed specifically for low conductivity waters.
The device has a unique leaching sleeve diaphragm, which allows quick response yet virtually no leaching of electrolyte, ensuring that quick and accurate responses are yielded.
The Aquatrode plus has internal shielding to reduce noise which could otherwise threaten the stability of the signal from the electrode. Request a free brochure from Metrohm UK ...
