A Comparative Study of Commercial ATP Hygiene Monitoring Systems Abstract The performance of 5 leading commercially available of ATP hygiene monitoring systems were compared in the largest independent study of its kind. Linearity, Sensitivity, Repeatability, Precision and Accuracy are the major requirements of an effective ATP system. These performance criteria were determined using many replicates and dilutions of ATP, foodstuffs and micro- organisms. The findings indicate that some of the systems show large variations and background interference which significantly affects their ability to meet the performance criteria. The best system was revealed to be Hygiena SystemSURE Plus and the poorest systems were Charm Novalum and Neogen Accupoint. Overview 1. Scope of the study Disclaimer: 2.
