3.3 Product Overview

The HM-KWS bioaerosol detector is an integrated detection device that combines a large-flow collection module, a rapid fluorescence detection module and a cleaning module. It is designed to solve the problems of traditional detection methods such as long detection time and complicated operation. It can realize fully automatic unattended detection (supporting scheduled multi-period detection every day), eliminating the need for manual separate sampling and the process of transferring to the laboratory for detection after sampling.

This detector is based on the firefly luminescence principle, using the "luciferase-luciferin system" to quickly detect adenosine triphosphate (ATP). Since the ATP content in living microorganisms is relatively constant, the ATP content can be determined by detecting the luminescence value, thereby determining the content of living microorganisms in the sample. During the detection process, the large-flow air sampling module first enriches the microorganisms in the air into distilled water, then adds a quantitative enzyme solution to the liquid. After full reaction, the rapid fluorescence detection module tests the relative luminescence intensity, and the corresponding microbial content can be calculated according to the luminescence intensity.

It supports both AC and DC power supply, which is convenient for long-term monitoring and mobile detection. It can also be connected to the network via WiFi (4G module is optional) to upload data to the cloud platform wirelessly. It is equipped with a data management platform to conduct long-term and short-term evaluation, management and analysis, and is widely used in various fields that require air microbial detection.

4. Core Technologies and Functional Features

4.1 Core Technologies

• Firefly Luminescence Principle-based ATP Detection Technology: This technology uses the specific reaction between luciferase and luciferin with ATP. Since ATP is a unique energy substance in living organisms and its content in living microorganisms is relatively constant, the luminescence value generated by the reaction is detected to invert the ATP content, and then the content of living microorganisms in the sample is determined. This technology skips the traditional microbial culture process, greatly shortening the detection time.

• Dry Wall Cyclone Gas-Solid Separation Technology: Applied in the large-flow air sampling module of the instrument, it can efficiently separate and enrich the microbial particles in the air into the lysate (distilled water). The collection efficiency is as high as 92%, which ensures the sufficient collection of microorganisms and lays a foundation for accurate detection.

• PMT Photomultiplier Tube Detection Technology: The detector adopts a PMT (Photomultiplier Tube) photomultiplier tube detector, which has high sensitivity to weak fluorescence signals. It can accurately capture the weak luminescence generated by the ATP-luciferase reaction, improve the detection accuracy of the instrument, and reduce the detection limit (the ATP detection limit can reach 10⁻¹⁰ to 10⁻¹⁸ mol ATP).

• Android Operating System Platform Technology: The instrument is equipped with the Android 7.1 operating system, with 2G RAM and 16G ROM. It has good compatibility and storage capacity, supporting the operation of various functional software (such as data management software, scheduled detection control software). The touch screen operation is convenient and fast, and it can realize human-computer interaction intuitively.

• Dual Power Supply Technology (AC and DC): The instrument supports 12V DC power supply (equipped with a 12V/10000mAh battery) and can also be powered by an AC power supply (matching a 12V/3A charger). This dual power supply mode makes the instrument suitable for both fixed long-term monitoring (using AC power) and mobile on-site detection (using battery power), improving the flexibility of use.

4.2 Functional Features

• Integrated Full-Automatic Detection: It integrates a large-flow collection module, a rapid fluorescence detection module and a cleaning module. It can complete the whole process of air sampling, microbial enrichment, reagent addition, reaction detection and automatic cleaning without manual intervention, realizing unattended operation.

• Scheduled Multi-Period Detection: The instrument supports setting multiple detection periods every day (the specific number can be set according to user needs). It can automatically start detection at the preset time, which is suitable for long-term continuous monitoring scenarios (such as environmental monitoring in clean workshops, public places, etc.).

• Rapid Detection and Automatic Data Reporting: The detection time can be adjusted between 2-180 seconds, and the detection results can be automatically calculated and reported after the detection is completed. The detection range covers 0-9999999 RLUs (Relative Luminescence Units), which can meet the detection needs of different microbial concentration levels.

• Wireless Data Transmission and Cloud Platform Connection: It supports WiFi network connection, and can upload the detected data to the cloud platform wirelessly. A 4G module can be optionally configured to realize data transmission in areas without WiFi coverage, ensuring the real-time and remote sharing of data.

• Data Management and Analysis: It is equipped with a dedicated data management platform, which can store, query, export and analyze the detected data (including long-term and short-term data evaluation). Users can view historical data, generate data reports and analyze data trends through the platform, providing a basis for decision-making.

• GPS Positioning Function (Optional): A positioning module can be optionally configured to record the geographic location information of the detection site while detecting. This function is especially suitable for mobile detection scenarios (such as on-site detection of biological emergency incidents), which is convenient for tracing the detection location and managing detection points.

• Lightweight and Portable Design: The instrument weighs 8KG, with an overall size of 337163480mm, and the packaging size is 550245375mm (packaging weight 10.5KG). It is small in size and light in weight, easy to carry and transport, and convenient for on-site detection in different locations.

• Automatic Cleaning Function: After the detection is completed, the instrument can automatically clean the sampling pipeline and detection module to avoid cross-contamination between different samples and ensure the accuracy of subsequent detection results.
