Introduction

The ATP fluorescence detector is based on the principle of firefly luminescence and uses the "luciferase luciferin system" to quickly detect adenosine triphosphate (ATP). Due to the constant amount of ATP present in all living cells, ATP content can clearly indicate the amount of microbial and other biological residues in the sample, which is used to assess hygiene conditions. The handheld ATP fluorescence detector has a wide range of applications and can be used in various industries such as food, medicine and health, pharmaceuticals, daily chemical products, papermaking, industrial water treatment, national defense, as well as environmental protection, water administration, customs entry and exit quarantine, and other departments.

In the field of food safety, handheld ATP fluorescence detectors are mainly used for rapid detection of food processing equipment, practitioners, food processing environments, microorganisms and hygiene conditions of food processing raw materials. The handheld ATP fluorescence detector is small in size and can be held by one hand, with simple and accurate usage. The results can be obtained within 1 minute, making it very suitable for rapid detection of food safety. Currently, handheld ATP fluorescence detectors have become the testing equipment of various levels of food and drug supervision and management departments. Mainly used for detecting microorganisms and hygiene conditions in food processing equipment, practitioners, food processing environments, food processing raw materials.

ATP rapid fluorescence detector

The ATP content in living microorganisms is relatively constant. This swab determines the ATP content by detecting the luminescence value, thereby determining the content of live microorganisms in the sample. This swab has two structures, with a cotton swab attached to the lower part of the connecting head of the surface swab. The cotton swab contains a bacterial lysis solution containing lytic bacteria and other microorganisms; The lower part of the connection head of the water sample collector is connected to a straw type water sample collector, and the sleeve contains bacterial lysate containing microorganisms such as lytic bacteria. The swab head contains enzyme reaction solution that can react with ATP to emit light. The cotton swab collects samples from the surface of objects or the water sample collector collects liquid samples, which react with bacterial lysate to release ATP from the microbial body. Then, they mix with enzyme reaction solution to produce reaction luminescence, which can be read by an instrument.
