Electroplating
Reliable analyses have a vital role to play in ensuring product quality in the metal working industry. Continuous monitoring of electroplating baths can help to prevent wastage.
Electroplated products are very common and can be found in many areas of everyday life from automotive parts and cutlery to trouser buttons.
Before they are coated, the unfinished parts have to be freed from traces of mechanical and chemical impurities. This is done using pickling and degreasing baths, which may be acidic or alkaline and contain surfactants and chelating agents. The electroplating bath itself contains heavy metals and conducting salts, which provide a durable coating in a defined pH range.
The various baths and the resulting wastewater have to be analysed throughout the entire process for impurities and pollutants in order to minimise any impact on the environment. The following parameters are monitored:
- pH
- Conductivity
- Temperature
- Heavy metals
- Cyanides
- COD
- Sulphates
- Nitrates
- Surfactants
We provide user-friendly, compact measurement systems for monitoring these parameters in the laboratory or directly on site. They contain photometers, sample preparation to break down the chelating agents and cuvette tests, as well as electrochemical instruments with digital electrodes, for example, which are detected automatically.
All system modules are extremely easy and straight-forward to operate, so even users with no chemical training can be sure of obtaining reliable results on a day-to-day basis.
