Adenosine triphosphate (ATP) hygiene monitoring systems detect levels of ATP from both microbial and non-microbial contamination on surfaces and liquid samples. The amount of ATP collected and read in systems is expressed in terms of relative light units (RLU). Variation in results between systems can be caused by the enzyme reagent formulation used to produce the bioluminescent reaction, the extractant pre-moistened on the swab bud, in the electronic calibration within the luminometer, and/or the variation in the sample being collected.
Understanding the correlation of ATP levels to RLU is important when comparing systems. Simple surface or water sampling comparisons can be highly variable due to sampling technique, surface type, sample type, and possible extreme variations in residue present in different areas on the same surface.
This Scigiene Hygiene Meter Evaluation Kit eliminates sampling error and provides a consistent and scientifically-based method for comparing systems by pipetting a stable consistent amount of ATP directly onto the tips of testing devices.
