Advanced ATP samplers utilizes ATP bioluminescence to determine the cleanliness of test samples. ATP
is a chemical compound found in all living cells, including bacteria, food debris, yeast, and mold. Bioluminescence is
a chemical reaction that produces light. ATP bioluminescence occurs when ATP from a sample comes into contact with
luciferase, an enzyme found in fireflies, and luciferin, a substrate. The amount of light emitted in this reaction is proportional
to the amount of ATP in a sample. Aer a sample is taken, the sampler is pressed into its cartridge, breaking its seal and
initiating the mixing of reagents. The reaction takes place within the cartridge, and a detector in the instrument measures
the amount of light produced. The reading is displayed on the screen in RLUs. According to preset limits, an icon is
displayed indicating a pass, marginal, or fail result. These limits are defined by the operator, by the company’s quality
system, or by using the system presets.
