MSE PRO™ Electrochemical Detector for Chromatography System, Model 2

Features

Advanced Noise Reduction Technology
Utilizes an Advanced Digital Filter (ADF), distinct from the traditional Filter Time Constant (FTC), which minimizes signal loss during noise reduction. This allows low-frequency peaks to pass while eliminating high-frequency noise, improving the signal-to-noise ratio and enhancing the detection limit.
Innovative Analytical Flow Cell Design
Features a central spray wall structure with continuously adjustable sensitivity. The working volume can be flexibly adjusted between 0 and 300 nL, enabling one electrode to support various sensitivity requirements.
Integrated Faraday-Shielded Temperature Oven
Reduces static interference, unexplained disturbances, and the impact of temperature fluctuations, enhancing repeatability and stability.

Additional Features

Suitable for IC, HPLC, and UHPLC systems.
Supports DC, PULSE, and SCAN detection modes.
Offers the highest sensitivity among electrochemical detectors.
Compatible with different flow cells to accommodate diverse applications.
