The ATP fluorescence detector uses some components in the ATP reagent, such as B. luciferin luciferase to react with the tested sample and generate photons, and then uses a specially designed fluorescence detector to detect and detect the luminescence value; p>
Since there is a certain functional relationship between the number of bacteria and other microorganisms contained in the examined sample and the ATP value contained, as well as between the ATP value and the luminescence value, the tested one is Luminescence value can be determined by detecting the luminescence value. Measure the level of microorganisms such as bacteria contained in the sample.
Sampling is one of the keys that affects accuracy and consistency. When you use it, you can refer to the handheld ATP meter manual for sampling, detecting, calculating, and recording the results.
In general, there are two types of sampling:
Surface type: place an ATP swab sampling stick on the surface of the object or curvature wipe Swipe the surface of both fingers back and forth twice from fingerball to fingertip (approximately 30 cm2 in one hand) and rotate the sampling swab accordingly.
Volume Type: Fully immerse an ATP swab in the liquid to be tested.
Post-sampling detection: Insert the swab into the portable ATP meter, detect the ATP bioluminescence value corresponding to the level of bacterial contamination of the tested sample and determine the hygiene status.
