Model 650 Conductivity Detector

Precise temperature control gives stable, drift-free baselines
Detects charged species at ppb levels
Compatible with suppressor-based and nonsuppressed methods

Unlike other conductivity detectors, the Model 650 can discriminate between random noise and the analyte signal, improving sensitivity. State-of-the-art signal processing and precise temperature control of the detection cell give stable, low-noise baselines. You can easily program and store up to 10 methods through the front panel controls, or control the detector digitally with SSI's EZStart data acquisition and control software.
