Get the benefits of performance and versatility provided by the CD25 Conductivity Detector’s unique features:
- CD25 cell geometry provides efficient sweepout, low volume, low dispersion, and excellent accuracy at both low and high conductivities.
- Low electrode mass in the conductivity cell allows for effective temperature compensation for improved reproducibility.
- The conductivity cell is mounted remotely at the end of the suppressor or column, minimizing dead volume.
- The optional DS3 detection stabilizer provides conductivity measurements that are nearly impervious to temperature variation for improved reproducibility.
- Use built-in control for the SRS® Self-Regenerating Suppressor, the most advanced suppressor for eliminating eluent detector background and providing high signal-to-noise ratio.
