Abstract
A system and process may be used to test water samples to measure ATP and/or estimate a microbial population, for example using an adenosine triphosphate (ATP) based assay. The system includes a device that is use in combination with single-use or disposable cartridges. The cartridge receives the water sample and is pre-loaded with one or more reagents. The device receives the cartridge and contains physical, electronic and/or mechatronic devices that interact with cartridge. One or more actions such as metering, mixing and conveying are performed automatically by elements of the device and/or cartridge. A sensor in the device measures light produced in the cartridge from a reaction with ATP in the water sample. Optionally, the cartridge also contains a pre-loaded amount of ATP, which is used to provide an internal reference or calibration measurement.
