Scope

Scope: This document specifies the working principle, performance requirements, and technical requirements such as marking, packaging, transportation, and storage for UV fluorescence biological aerosol monitors. This document applies to a class of optical monitors (hereinafter referred to as "monitors") that use UV light to excite the intrinsic fluorescent groups in microbial cells to measure the concentration of microbial aerosols. Main technical content: The standard emphasizes the basic structure, types, performance requirements, technical requirements, and principles of performance inspection for biological aerosol samplers. It provides the working principle of real-time biological aerosol monitors, which uses the mechanism of UV laser excitation to induce fluorescence emission from biological fluorescent molecules in microbial cells. Based on optical information such as the amplitude of elastic scattering light pulses, the size of the measured biological aerosol particles is determined. The biological properties of the measured particles are judged based on the intensity of the fluorescence pulse signals, and biological particles are distinguished from non-biological particles. The number of pulses corresponds to the number of biological particles, and the concentration of biological particles is measured and recorded. It also describes the main components of real-time biological aerosol monitors, including air sampling systems and gas paths, UV light sources and optical paths, photoelectric conversion systems, electrical signal analysis and processing systems, and data output and display sections, etc.
