A small but very efficient accessory: With the Post-Column Reactor (PCR), post-column derivatization can be carried out reliably and reproducibly. The colored reagent is added by the 833 IC Liquid Handling Pump Unit. The built-in pulsation absorber ensures a stable reagent flow. Some standard methods require color reactions. With the PCR it is possible, for example, to determine chromate and bromate down to very low concentrations. Very interesting application possibilities are also to be found in the field of cation analysis using UV/VIS in addition to conductivity detection.
