Abstract

Methods and apparatus for evaluating the quality of a sample of a product, an ingredient, an environment or a process by measuring multiple parameters thereof, including light emitted from a reacting sample containing ATP, ADP, alkaline phosphatase or other parameters such as pH, temperature, conductivity, oxidation reduction potential, dissolved gases, specific ions, and microbiological count. The apparatus comprises an integrated sample testing device used to collect a sample, mix reagents, react the sample, and collect it in a measurement chamber. The apparatus also comprises an instrument having a photon detection assembly for use with the sample testing device. The instrument can also comprise one or more sensing probes and a communication port to facilitate data collection, transfer and analysis. The method further comprises a mechanism for storing data, evaluating data, graphing data, and determining conformance to established criteria.
