Due to the critical role of chemical composition in the performance of membranes, controlling and analyzing substances for the production process is an indispensable procedure.

Chemical analysis enables quality control of all raw materials used in the membrane production process. Consequently polymers and solvents as well as additives and all adjuvants are closely checked. In addition, the regular analysis of our products, for example the control of residual solvent contents in finished goods, is part of the laboratories’ tasks.


Some of the chemical tests conducted are:

  • Analysis methods
    • Differential Scanning Calorimetry (DSC)
    • Gas Chromatography with Mass Spectroscopy (GC-MS)
    • High Performance Liquid Chromatography (HPLC)
    • Inductively Coupled Plasma Atomic Emission Spectrometer (ICP) and Atomic Absorption Spectrometer (AAS)
    • MoistureAnalysis System according to Karl-Fischer
    • Total organic carbon (TOC)
    • Viscosity Measurement
  • Water analysis
    • Biological Oxygen Demand (BOD)
    • Chemical Oxygen Demand (COD)
    • Silt Density Index (SDI)
