GE AKTA pH/C-900 Combined pH and Conductivity Monitor for Liquid Chromatography
Product Description
The GE AKTA pH/C-900 Monitor is designed for precise, online monitoring of pH and conductivity during liquid chromatography. Key features include:
- Accurate measurement of pH, conductivity, and temperature
- Integrated temperature compensation to correct pH and conductivity readings
- Low cell volume and high linearity in both pH and conductivity/temperature flow cells
- Suitable as a standalone instrument or integrated in ÄKTAdesign chromatography systems
- Equipped with self-diagnostics for continuous reliability and reproducibility
- Note: pH electrode is not included and must be acquired separately
This instrument ensures accurate elution condition monitoring critical for chromatographic separations.
