Frequently Asked Questions (FAQs)

1. What is the purpose of air sampling?

Air sampling is carried out to ensure that workplace or environmental air is meeting regulatory standards and to help Occupational Hygiene and Health & Safety professionals assess employee exposure to airborne hazards.

2. What is meant by air sampling?

What is the definition of air sampling? Air sampling is a process used to determine what airborne contaminants are present in an environment. It uses special instruments to detect contaminants such as gases, vapors, dusts and fibers in the air.

3. How does an air sampling cyclone work?

Unlike other air sampling equipment that simply draws air across a filter, the cyclone is a device that creates a centrifuge. This rapid air circulation allows larger particles to fall down into what's known as a grit pot, while smaller, respirable-sized particles are captured by the filter cassette.

4. How is air sampling done?

In active air sampling, air is passed through a tube that is filled with a solid sorbent material. The sorbent material chemically absorbs the contaminant(s). A sampling pump is used to collect an air sample through this method. Passive air sampling is the opposite of the active sampling technique.
