Pulsed Amperometric Detector
Optimum for High-sensitivity Analysis of Carbohydrates and Polyols!
Derivatization and other complex pretreatments are not necessary. The sensitivity is about 10 to 100 times greater than that of a differential refractometer.
Double-layered Reference Electrode (Patent Pending)
The detector has a double-layered reference electrode so that (1) will not be placed in direct contact with the mobile phase. Therefore, an organic solvent can be used for the mobile phase simply by changing the outer cylinder liquid to NaCIO4 solution.
Excellent Sensitivity with Cell Developed for Semi-microcolumn
A cell structure suitable for semi-microcolumn HPLC is adopted. Compared with a conventional column (4.6 mm i.d.), the analysis sensitivity is about 5 times greater.
Example of sensitivity increase in semi-microcolumn HPLC
The detector can also be used as a conventional high-sensitivity electrochemical detector by changing the mode.
Since ordinary amperometric mode is also supported, the detector can be used for conventional electrochemical detector applications.
Easy Maintenance
The unique electrode design allows maintenance with no tools.
Gradient Analysis
The unique reference electrode design permits the mobile phase of non-water solvent and gradient analysis.
