In the control laboratory, the testing of active agents and adjuvants as well as the testing of packing materials, from semi-manufactured goods up to the finished product are performed using validated methods on qualified calibrated instruments and the quality is evaluated. Chromatographic methods such as HPLC and GC as well as fully automatic discharge instruments in particular are used for the chemical-physical tests. New products as well as those already on the market are monitored by regular stability testing over the life-span of the products.
