Abstract
A disposable sensor for metal analysis comprises a housing including a first section, a second section, and a flexible intermediate section therebetween. An ampoule containing a reagent is disposed in the intermediate section. A liquid seal is formed between the first and second sections. The intermediate section of the housing of the disposable sensor may be flexed to break the ampoule. When the seal is broken between the first and second sections, and the water (or any other liquid) sample mixes with the reagent, the mixture flows into the second section containing an electrode assembly. The electrode assembly may be disposed in engagement with the monitoring device to determine the concentration of the at least one metal in the water (or any other liquid) sample.
