Chemical testing

Chemical testing

  • Assays (e.g. UV spectrophotometer, AAS, titration)
  • Chromatographic tests (HPLC (UV/VIS-DAD, RI, EC))
  • Identification of active ingredients and impurities
  • Physical and physio-chemical determinations (e.g. pH,
    conductivity, viscosity, melting point, refractometer, polarimeter, sub-visible particle counter, osmolality, loss on drying)
  • Specific equipment for nasal sprays (automatic dosage control, droplet size distribution)
  • Limit tests (e.g. heavy metals, sulphated ash, anions)
