IONUS Post Colum Derivatization (PCD)

The IONUS Post Colum Derivatization (PCD) does not have a built- in conductivity detector. Instead, it has a reactor for derivatization followed by a single wavelength photometer. These single wavelength photometers are very sensitive compared to a variable UV/VIS detector, and it can be easily changed by the user. The choice of wavelength depends on the selected colour reaction, such as for the two bromate determination according to EPA 317 or 326 with 440 nm or 355 nm. For the determination of Chromium (III)/(VI) 340 nm or 530 nm are used. The IONUS PCD also offers the advantage that it can be used with IC columns of al manufactures and it is compatible with all common eluents of anion and cation chromatography
