Contactless Conductivity Detection C4D

C4D enables conductivity measurement without direct contact with the liquid. With C4D, extremely small sample volumes can be measured — as little as 20 nanolitres. The system supports a wide measurement range, from 10 µS/cm to 1000 mS/cm. 🌟 Key Advantages of Contactless Conductivity Detection 🧪 No Direct Contact with the Liquid No contamination or interference with the sample. Ideal for sensitive, reactive, or biological samples. 🧼 No Fouling, No Scaling Electrodes remain clean because they are not in contact with the fluid. Resistant to dirt, scaling, and biofilm formation. Minimal maintenance – no frequent cleaning or recalibration required. 🧯 Safe and Chemically Resistant Suitable for aggressive or corrosive media . safer in hazardous or flammable environments. ⚙️ Robust and Reliable in Harsh Conditions Performs well in dirty, high-solid, or high-viscosity samples, such as slurries or wastewater. Stable performance with low drift and long-term accuracy. No carryover or "memory effect" from previous samples. 🔬 Applications and Product Range EDAQ’s contactless conductivity technology is available in a range of formats to suit various applications: Capillary Electrophoresis (CE) High-Performance Liquid Chromatography (HPLC) Flow Injection Analysis (FIA) Ion Chromatography (IC) Microchip Electrophoresis (MCE) Microbial Growth Monitoring For system integrators and instrument manufacturers, EDAQ offers OEM modules — compact PCB-based detectors designed to be embedded into third-party systems.
