In cleanroom environments, controlling the concentration of airborne particles (dust) plays a crucial role in ensuring product quality and human health safety. Air particle measurement is the process of counting and analyzing the size and quantity of dust particles present in the air at a specific moment. This process allows us to assess the pollution levels in cleanroom environments and implement appropriate control measures. Let’s explore detailed information about measurement parameters, methods, and considerations when measuring airborne particles with INTECH Service in this article!
What is Air Particle Measurement?
According to ISO (International Organization for Standardization), airborne particles are tiny solid substances suspended in the air. These particles can vary in size from a few nanometers to several hundred micrometers.
Air particle measurement is the process of determining the quantity and size of suspended dust particles in the air. This process is carried out using specialized devices called particle counters.
Essential Metrics for Measuring Airborne Particles
Particle Concentration
This is the most important metric, indicating the number of dust particles per unit volume of air. Particle concentration is measured in particles per cubic meter (particles/m³).
Particle Size
Particle size is also a crucial factor that affects the impact of dust particles on human health and the environment. Particle size is measured in micrometers (µm) and is divided into several ranges, typically from 0.1 micrometers to 5 micrometers.
Additionally, some other metrics may be considered when measuring airborne particles, including:
Humidity: Humidity can affect the size and properties of dust particles.
Temperature: Temperature can influence the distribution of dust particles in the air.
Wind Speed: Wind speed can affect the sampling of dust particles.
Important Considerations When Measuring Airborne Particles
Ensure Proper Calibration
Particle measuring equipment must be regularly calibrated according to the manufacturer’s guidelines and international standards, such as ISO 21501-4. This ensures the accuracy of the measurement results.
Choose Sampling Locations Carefully
Sampling locations significantly impact measurement results. Select locations that accurately reflect the operational conditions and characteristics of the area being measured. Avoid sampling in places influenced by localized pollution sources or uneven airflow.
Perform Accurate Sampling Procedures
Air sampling must be conducted according to precise and consistent procedures, including setting the sampling time and the volume of air to be collected. These factors are crucial for accurate and reliable particle measurement results.
