Ion chromatograph system LICS-A20 is a modular design ion chromatograph with an upgraded circuit technology. Bipolar conductivity detector, improves the detection performance and stability of the instrument. It has a detection range of 0 to 45000 µS/ cm and detection resolution of ≤ 0.0020 nS/ cm with a cell voloume of ≤ 0.8 µL and a baseline drift of ≤ 3 % FS/ 30 min. Gradient elution system detects small molecules from complex samples. Built-in circulating stereo constant temperature and other technologies ensures accurate and reliable experimental data.
