New method in the field of chemical-filmic surface cleanliness


Determination of ionic contamination

The investigation of ionic impurities is an underestimated, yet important sub-area. The increasing use of highly sensitive and compact electronics in the technically demanding automotive sector (fluctuating temperature/climate requirements) places increasingly stringent demands on the cleanliness of such components. Salt residues from soldering or electroplating processes often lead to corrosion damage.

CleanControlling has expanded the service portfolio with the determination of ion-specific amounts of dissolved salts by means of IC (ion exchange chromatography). The IC is a powerful tool to characterize various saline impurities and to quantify them in the ppm range.
