ATP Surface Testing & Hygiene Verification in Orange County, FL
ATP testing in Orange County is used for rapid hygiene verification by detecting biological residue and contamination levels on surfaces using bioluminescence testing. ATP (Adenosine Triphosphate) is a molecule that can be found in every living cell. Its presence on surfaces indicates whether cleaning methods have been successful at removing bacteria and other health risks.
Our team uses the latest technology to perform ATP cleaning tests. This allows us to quickly and accurately assess the cleanliness of different surfaces.
This method not only helps identify areas that require more cleaning, but also gives you peace of mind knowing that your environment is up to the highest standards of hygiene. In today's environment, cleanliness is essential for safety and health.
While many methods exist for evaluating cleanliness, ATP bioluminescence is the only method that combines quantitative data collection with scientific measurement and still delivers speedy results.
- Speed– Real-time analysis yields actionable information in seconds.
- Linearity– There is a direct, proportional, straight-line relationship between RLU and ATP.
- Repeatability– There are dependable results with a low coefficient of variation (CV).
- Sensitivity– The is an extremely low Limit of Detection (LoD) allowing for identification of low levels of ATP above background noise.
- Accuracy– Based on a comparative study of commercial ATP Hygiene Monitoring Systems2, the ATP system used by FSG Inspections is the closest to 100%, thus the least variable and most accurate in the study.
