Introduction

The pH/C-902 Monitor is a high precision on-line monitor for
measurement of pH and conductivity in high performance liquid
chromatography applications.

The monitor is suitable for pH and conductivity measurements in
pharmaceutical applications where monitoring of running conditions
is critical.
The pH/C-902 Monitor is a combined monitor with two independent
measuring channels for both pH and conductivity.
The pH/C-902 features:

Two separate pH measuring channels

Two separate conductivity measuring channels

Fast response

High accuracy and reproducibility

Flow cells with small dead volume

Flow cells that can be connected close together, minimizing band
broadening and time delays between detectors.

Control via UNICORN™ software only.

Safety

The instrument is designed for indoor use only

Do not use the instrument in a dusty environment or close to
spraying water

Only use the instrument in accordance with local safety
regulations
