SWAN Analytische Instrumente AG

SWAN Analytische Instrumente AG is a Swiss manufacturer established in 1991 and based in Hinwil, specializing exclusively in continuous online analytical instrumentation for water quality monitoring. All SWAN instruments are engineered, assembled, and tested in Switzerland under ISO 9001:2015 certification. The company's product portfolio is organized around the AMI (Analytical Measurement Instruments) series of online analyzers and the Oxycon family of compact analyzers and reagent systems. Measured parameters span silica (AMI Silitrace and COPRA lines), dissolved oxygen (AMI Oxysafe with Clark cell technology), pH and redox/ORP, conductivity (four-cell principle, AMI Solicon), sodium, fluoride, phosphate, ammonium/nitrate, free and combined chlorine (Oxycon Chlor with TRIDES amperometric and CODES photometric detection), ozone, and carbonate hardness. A distinguishing feature is SWAN's plug-and-play design philosophy: instruments ship pre-configured and factory-calibrated, with automatic cleaning routines to minimize maintenance. The CHEMATEST portable photometer serves as a field verification tool for online disinfection monitors. SWAN serves seven core industries—power generation, industrial process water, potable and municipal wastewater, pharmaceutical, semiconductor ultra-pure water, pool water, and food and beverage—with a stated vision of becoming the global competence center for process water analysis.
