What `Total` means, in heavy metal detection
For in-process and on-line measurements of heavy metal content in industrial samples there is no time for special and time consuming laboratory-type sample preparation. All sample preparation must be done continuously in one step:
- Interference influences must be eliminated.
- Oxidation stages have to be taken into account (or separated and excluded).
- Complexes have to be destroyed to free the heavy metal ions for measurement.
- Suspended particles must become dissolved again (or separated and excluded).
In SEIBOLD on line analysers this most important step is achieved by using our unique and proprietary reagents (buffers and dye).
