MSE PRO™ Ion Chromatography System Model 4

Features

Cation and Anion Dual-Channel System: Both channels operate independently, ensuring no interference between them, allowing simultaneous detection of cations and anions.
Eluent Thermal Buffer System: Preheats the eluent before it enters the columns, preventing bubble formation caused by rapid heating.
Built-In Low-Pressure Degassing Technology: Eliminates bubble interference, enhancing system stability.
Advanced Chromatograph Column Series: Offers a full range of columns capable of detecting ions with diverse compositions.
Exceptional Performance: Designed to support all your application needs efficiently
