ATP (adenosine triphosphate) fluorescence detector

Abstract

The invention discloses an ATP (adenosine triphosphate) fluorescence detector, which comprises a housing with an opening in the top, wherein a lighttight box is fixedly arranged at a position, below the opening, of a bottom plate of the housing; the lighttight box is provided with a detection position where a detection chip is disposed, and a detection hole is formed in the detection position; a centrifugal motor and a mounting plate are arranged in the lighttight box, wherein the centrifugal motor is used for driving the detection chip for centrifugation; the mounting plate is provided with alight-transmitting hole switching mechanism; the light-transmitting hole switching mechanism comprises a switching motor and a detection component which are fixed on the mounting plate; the detectioncomponent is provided with a lens and a switching hole plate; the switching hole plate is provided with a plurality of light-transmitting holes of different sizes in sequence in a length direction; the switching motor is used for driving the switching hole plate to move in the length direction; and the amount of light entering the lens is adjusted by switching the different light-transmitting holes. According to the ATP fluorescence detector, the amount of fluorescence entering the detector can be adjusted according to the generation amount of fluorescence, and the ATP fluorescence detector can adapt to different detection requirements.

Description

technical field [0001] The invention relates to the technical field of fluorescence detection equipment, in particular to an ATP fluorescence detector. Background technique [0002] ATP (Adenosine Triphosphate), the Chinese name is adenosine triphosphate, also known as adenosine triphosphate. It is ubiquitous in microbial cells such as bacteria, and ATP is an energy substance for microbial metabolism. The ATP bioluminescence method uses several components in the ATP reagent, such as luciferin-luciferase, to react with the tested sample to generate photons, and then uses a specially developed device to capture and detect the luminescence value. Due to the bacteria contained in the tested sample There is a certain functional relationship between the number of microorganisms and the contained ATP value, and between the ATP value and the luminescence value. Therefore, the content of bacteria and other microorganisms contained in the tested specimen can be obtained by detecting ...
