Abstract
A chemical indicator solution, an apparatus, and a method for determining concentration of a chemical analyte is provided. In particular, the apparatus provides a simplified and low cost way to determine that a fluid sample contains a minimum recommended concentration of a chemical. Rather than using complex and expensive components or error-prone manual methods to prepare the solution and measure chemical concentrations, the apparatus may allow for the automatic measuring and mixing of the chemical components of the resulting solution through the unique geometry and layout of the apparatus. The resulting solution may contain a chemical indicator which allows for the detection of the concentration of the chemical analyte within the resulting solution using techniques such as color analysis.
