Abstract: Embodiments of the present invention are directed to methods, systems, and software for assessing contaminant quantities in a fluid. Fluid enters a reaction chamber. A controller then signals two different sheets with different reagents to move into the reaction chamber. One sheet contains reagents to form a contaminant byproduct or gas, while the other sheet is saturated with reagent that will have a photometric effect upon reacting with the contaminant byproduct or gas. After the photometric effect has occurred, the controller moves the reacted portion of the other reagent sheet into alignment with a photometric sensor. This photometric effect is calculated to contaminant concentration. The concentration is recorded and the data is transmitted to memory. The fluid sample in the chamber is drained and the remaining solid waste is collected onto the first reagent sheet. Both sheets are individually collected into separate controllable collectors.
