The PowerChrom or e-corder can be connected to ion chromatography (IC) instruments. The C4D Amp can be added as a contactless conductivity detector.


Ion chromatographs that have an analog output can be connected to either the PowerChrom or e-corder unit. The PowerChrom software is then used to record and analyse the data.

The ion chromatograph’s “Inject” port can also be connected to the PowerChrom or e-corder, to trigger the start of recording.

Add the eDAQ C4D Amp and you can detect your analytes with contactless conductivity detection.

Ion Chromatography with C4D Detection

Figure 3 shows the e-corder and EA120 C4D Amp connected to the Metrohm 792 Basic IC instrument.

Conductivity detection can be used for virtually all charged species: inorganic anions and cations, as well as organic ions, such as carboxylic acids, amines, amino acids, peptides, proteins, DNA fragments, antibiotics and many other pharmaceutical compounds.
