In many industries, such as pharmaceuticals, mining, and construction, air samples are important for analyzing the concentration of dust and other hazardous particles that can be detrimental to both business operations and employees. Air cassettes can be used to assess the risk of these dangers. These small devices allow users to collect a representative sample of air particles in a specific environment that help identify that an area is conducive for working and business operations.
In this post, we explore what air cassettes are and how they are utilized for air sampling.
What Are Air Cassettes?
Air cassettes are devices that are used to collect and measure the atmospheric make-up of air in a particular environment or indoor area. Although applications extend to various industries, they are generally used by health and safety professionals to consider the health and safety aspects of a particular environment or workplace setting. Air cassettes can be used in virtually any orientation.
The air cassette is able to provide a comprehensive analysis of air particle distribution by collecting and identifying a variety of air particles. Among these are:
- Metal particles
- Fly ash
- Skin cells
- Mold spores
- Insect parts
- Pollen and more
Once the sample of air particle distribution is collected, it is then sent to laboratories where it is examined by professionals.
How Is Air Sampled?
The air sampling process is done in two phases. First, the air sample is taken in the area that is suspected to be of poor air quality. A second control sample is taken outdoors or an area that is not considered to have poor air quality.
It is important to note that the air sample collected and the representation of air particles present is only a snapshot at a particular time. Therefore, to ensure more accurate representation of particles, technicians will likely need secondary samples at different times and areas to make more accurate inferences. The results of the secondary samples are then analyzed and evaluated to identify the extent of air quality problems in the first air sample.
Gathering air samples for dust analysis requires different sampling times depending on the environment where the test is conducted. Professionals will typically refer to a chart to ensure they are using the correct sampling time.
Air cassettes, such as the Air-O-Cell Sampling Cassette, are designed to use the latest engineering and efficient air collection and sampling methods to ensure air particle sample distribution meets the highest standards and requirements of accuracy and reliability.
