Quality control of basic chemicals and raw materials

Quality assurance in production begins when the basic chemicals used are checked. Analytical instruments from Metrohm make it possible to

  • establish the concentrations of acids or bases reliably, quickly and easily,
  • determine the metal content of various raw materials or
  • detect any impurities in trace quantities.



Typical applications for quality control of basic chemicals:

Titrimetric applications
Sulfuric acid, hydrochloric acid, sodium hydroxide, ammonia and hydrogen peroxide content in basic chemicals
 
Ion chromatographic applications
Impurities in hydrogen peroxide, isopropanol, etc.
Determination of ultratraces
 
Voltammetric applications
Traces of heavy metals in basic chemicals
Nickel in sodium hydroxide by means of adsorptive stripping voltammetry (AdSV)
