Surface and Swab Testing

Surface and Swab 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 your requirements. Analysis is routinely performed on a range of organic and inorganic air contaminants and a wide variety of microbiological contaminants.

Swab testing and surface sample testing is 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
