About the Lab
Air Quality Testing
The air quality testing service is also routinely used to monitor the air quality of a workplace and is used as a useful technique for ensuring a healthy and safe environment for employees. The air quality laboratory analyses sample tubes, badges, filters and impinge solutions for a wide range of compounds of interest in OS&H monitoring. Example of these compounds are metals ( e.g. lead, mercury), hydrocarbon solvents, benzene ( e.g. petrol station attendant monitoring), alcohols, ketones, chlorinated solvents, formaldehyde, etc.

Swab & Surface Sample Testing
Our Air Quality laboratory regularly tests swab and surface samples. A wide variety of compounds can be tested for chemical and microbiological contaminants. If you are evaluating spraying, wanting to understand the nature of deposits or monitor cleaning processes we’ll have a swab and surface sample test to meet you requirements.
Swab and surface sample testing in routinely used for:
- Surface contamination monitoring
- Evaluating spray drift
- Understanding the nature of particulate deposition
- Monitoring cleaning efficiency
- Answering a range of other monitoring questions
Analysis is routinely preformed on a range of organic and inorganic air contaminants and a wide variety of microbiological contaminants.
We are always developing new test in this area. If you can’t immediately find a surface test to meet your needs call us on the number below and we’ll discuss a development option with you.
