Contactless Conductivity Detectors C4D

Unlock the Power of Contactless Detection with eDAQ’s Capacitively-Coupled Conductivity Detectors (C⁴D)

eDAQ offers advanced Capacitively-Coupled Contactless Conductivity Detectors (C⁴D) designed to bring precision, versatility, and ease-of-use to your analytical workflows. Whether you're working with capillary electrophoresis, microchip electrophoresis, chromatography or flow injection analysis. eDAQ C⁴D systems provide a powerful, non-invasive solution.

Why Choose Contactless Conductivity Detection (C⁴D)?

Non-invasive & contamination-free: No direct contact with the sample eliminates electrode fouling and minimizes maintenance.
Exceptional sensitivity: Detect ionic species accurately—even at trace concentrations.
Compact & compatible: Perfect for miniaturized systems like capillary and microchip electrophoresis.
Versatile & modular: Seamlessly integrates with a wide range of analytical platforms and applications.
Real-time analysis: Ideal for continuous, in-line monitoring of flow-based systems.
