Description

technical field

[0001] The invention relates to a water quality analysis method and device, in particular to a water quality analysis method and device capable of subtracting background interference when no sample pretreatment is performed. Background technique

[0002] Microbiological detection is an important part of environmental or food safety assessment. Among them, the total number of bacteria, coliform bacteria and pathogenic microorganisms are internationally recognized health detection indicators, which are important scientific basis for judging whether the environment or food is safe. Microbial detection can correctly evaluate the degree of microbial contamination of the environment or food, provide scientific basis for various health management work, and provide important scientific guidance for the targeted prevention and treatment of related diseases to ensure people's health; It is of great significance to the environment or food quality, to avoid economic loss...
