Another technique is microscopy, where samples are collected on filters and then analyzed under a microscope to count and measure the particles directly. This method provides detailed information about the shape and composition of the particles but can be time-consuming.

Another sophisticated technique is the use of cascade impactors, which separate particles based on their size using a series of impaction plates. Each plate collects particles of a specific size range, allowing for size-resolved measurements. This method is particularly useful for assessing the size distribution of particles in a sample. In addition to these methods, researchers also use advanced techniques such as scanning electron microscopy (SEM) and transmission electron microscopy (TEM) to obtain high-resolution images of the particles and analyze their chemical composition. These techniques provide valuable insights into the nature and origin of the particles.

The choice of measurement technique depends on the specific application and the type of information needed. For example, if the goal is to monitor air quality in real-time, OPCs are a good choice due to their ease of use and rapid response time. If detailed information about the shape and composition of the particles is needed, microscopy or electron microscopy may be more appropriate. Regardless of the method used, accurate measurement and detection of 20-micron particles are essential for understanding their impact on human health, the environment, and industrial processes. By employing these techniques, we can gain valuable insights into the behavior and characteristics of these tiny particles and develop effective strategies to manage and control them.
