The RS1 is designed to perform fully automated colorimetric measurements and deliver the product of the chemical reaction to an analysis cell in a process setting. The system first retrieves a known volume of sample from a stream and mixes it with up to three reagents in succession. After each reagent addition, a mixing cycle is performed followed by a variable reaction delay. Once the reagent addition process is complete, the final solution is transported to a heated measurement cell where the compound of interest can be determined via an absorbance measurement. The RS1 is designed to be mounted near to the pipeline containing the sample of interest which is retreived from the pipeline via a fast loop.
