Target measure of total biomass with ATP





ATP 2G, which guarantees detection of all living micro-organisms, is among the most reliable technologies for determining the total biological content of a water or fluid.

Unlike genetic analyses that rely on DNA specificity, or immunological analyses that rely on antigen specificity, ATP measurement does not specifically identify any microbial species. The ATP molecule is common to all living things.

However, ATP-metry generates an extremely reliable indication of the total number of living micro-organisms, also referred to as total biomass, total biological burden, or total active flora.

ATP 2G detects 100% of live micro-organisms

The range of micro-organisms detectable by ATP 2G technology is among the largest possible, as it can detect 99.9% of micro-organisms found in liquid environments.

Other analytical technologies

The biological burden of a water sample is traditionally determined in a laboratory by analyzing aerobic micro-organisms that grow at 22°C or 36°C on solid media (NF EN ISO 6222). This technique allows quantification of the many aerobic bacteria that are viable and cultivatable under the given conditions (expressed as the number of CFUs or Colony-forming Units). However, many live micro-organisms cannot be quantified using this methodology.
