ProcessLab in Action: Applications
Thanks to Metrohm’s many years of experience in the
field of ion analysis, we are able to measure numerous analytical
parameters, of which the following are particularly important
in process analysis:
- pH value
- Conductivity
- Redox potential
- Acid content
- Free and total alkalinity
- Water hardness
- Phosphates
- Chloride
- Chlorine
- Ammonia
- Nitrite
|
- Fe, Cu, Ni, Zn
- Na, Ca, F (with ISE)
- Free and total SO2
- Sulfate
- H2S / mercaptans
- Hydrogen peroxide
- Free fatty acids
- Surfactants
- Water content (Karl Fischer)
- Organic additives (CVS)
|
All analytical methods that are already used in the lab can
easily be transferred to process analysis.
The modular ProcessLab system can be used for a wide range
of different applications. Numerous applications have already
been successfully implemented. A small selection of these
is given below.
