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)
