Air Sampling involves drawing a known volume of air through a filter, trapping the contaminants and measuring the amount of contaminant captured. The results are usually expressed as a concentration, calculated by dividing the volume of air by the amount of contaminant captured. To calculate the volume of air, you multiply the flow rate (usually expressed in Litres Per Minute) by the duration of the sample. For this reason, the air sampler must be carefully calibrated before use to ensure the flow rate is correct. Often, multiple samples are required to provide a better understanding of the environment.
There are many different devices which can be used for air sampling:
In some industries, these instruments are a legal requirement in order to detect the concentration of potentially harmful airborne substances within an worker’s breathing area. These include aerosols, dusts, fumes, smokes and mists. All are a danger to health, as small particles can settle on the lining of the lungs, causing respiratory problems.
By taking air samples, employers can ensure their workforce are safe from exposure to airborne contaminants. This is a legal requirement in many industries.
