The impaction air sampler uses a progressively increasing humidity environment to significantly improve the survival rate of vulnerable pathogens (such as viruses), ensuring high-fidelity sampling.
Precise Grading, Biomimetic Sampling
- The impaction air sampling employs a six-stage impaction structure, with each stage corresponding to microbial particles of different size ranges. It can accurately collect particles from 0.65 μm to >7.0 μm, mimicking the deposition behavior of different-sized particles in the human respiratory tract, comprehensively reflecting the size distribution of microorganisms in the air.
- The air sampler machine is designed based on the anatomy and aerodynamics of the human respiratory tract. The first two stages simulate the upper respiratory tract, and the last four stages simulate the lower respiratory tract, enabling the assessment of microbial penetration and deposition potential within the respiratory tract.
- The air sampling equipment boasts a capture rate exceeding 98%, and its circular nozzle design enhances sampling efficiency. The relative humidity gradually increases during sampling (39%~88%), which is conducive to the survival of vulnerable microorganisms (such as viruses), improving detection reliability.
Reliable Performance and Easy Operation
- The impactor air sampler is applicable to a wide range of scenarios, meeting diverse monitoring needs: it is widely used in disease prevention and control, environmental protection, pharmaceuticals, fermentation industries, food industries, and bio-cleanliness, while also meeting the air microbial sampling research needs of scientific research and teaching departments, providing scientific data support for environmental microbial pollution assessment and remediation.
- The impaction air sampler boasts stable sampling performance with adjustable and controllable parameters: the standard sampling flow rate is 28.3 L/min, allowing for flexible adjustments to adapt to different scenarios; equipped with a DC12V power supply (35W), it operates stably with moderate energy consumption. The sampling duration can be precisely set via a timer, requiring no manual intervention and automatically completing the sampling process.
- Its user-friendly design balances practicality and safety: the entire system consists of a six-stage impactor, main unit (flow meter), timer, and tripod, featuring a compact structure for easy portability and on-site deployment. Flow calibration can be quickly performed before sampling, saving manpower.
Applications
Air samplers have a wide range of applications, which can be summarized into four main areas: In environmental monitoring, they are used to track air quality in cities and regions over a long period of time and assess the status of pollutants such as PM2.5 and ozone; in industrial safety, they monitor toxic and harmful gases and dust in working environments such as chemical plants and mines in real time to protect occupational health; in public health, they provide a basis for disease prevention and control and environmental sanitation; and in fire early warning systems, they enable early warning of fires to protect life and property.

Q1: What are the Key Parameters of an Air Sampler?
A1: The core parameters of an air sampler include: sampling flow rate (including stability and accuracy, with constant/medium/low flow rates to suit different scenarios), sampling time (precisely settable and cumulatively timed), and compatibility with the sampling medium (compatible with filter membranes, adsorption tubes, etc.). In addition, flow rate calibration accuracy, negative pressure tolerance, operating temperature and humidity range, air path sealing, and the battery life of portable models and the continuous operation stability of stationary models directly affect sampling accuracy and applicable scenarios, making them key selection criteria.
Q2: What is the Correct Operating Procedure for an Air Sampler?
A2: Before the operation, check the air circuit sealing, battery/power supply status, and calibrate the flow rate. Install the appropriate filter membrane or adsorption tube as needed, ensuring a secure and leak-free installation. Set the sampling flow rate, time, and other parameters, and aim the sampling head at the target area (avoiding obstructions and strong airflow). After starting the device, observe its operating status. Avoid touching or moving the instrument during sampling. After sampling, promptly remove the collection medium and seal the label. Turn off the device, clean the sampling head and air circuit, and record the usage to ensure sample integrity and future device usability.
Q3: What Factors can interfere with the Use of Air Samplers?
A3: How often the probe of a dew point meter needs to be cleaned depends on a variety of factors, including the environment in which it is used, the frequency of use, the cleanliness of the sample gas, and the specific requirements of the instrument. Here are the steps to clean the probe. Air samplers are susceptible to interference from multiple factors: Environmentally, high temperature, high humidity, and strong airflow can affect sampling stability; dust or corrosive gases may clog the air path and damage components. Operationally, flow calibration deviations, improper installation of the sampling medium, and obstruction or improper positioning of the sampling head can lead to sample distortion. Equipment-wise, air path leaks, pump aging, sensor drift, and insufficient battery life (for portable models) can reduce sampling accuracy. Furthermore, unreasonable sampling time settings and ambient electromagnetic interference can also interfere with normal operation and data accuracy.
Tips: Why is the Air Sampler Important?
Air samplers are a key tool for monitoring and assessing environmental safety. By actively collecting harmful substances such as microorganisms and dust from the air, they transform invisible pollution into quantifiable data, providing scientific evidence for public health, disease prevention, pharmaceuticals, and the food industry. Especially today, with increasing attention being paid to airborne microbial pollution, accurately measuring the quantity and particle size distribution of microorganisms is crucial for assessing their potential harm to human health and developing effective protective and remedial measures. It is an indispensable first line of defense for ensuring environmental safety and human health.
