Background: Preparation of the test atmosphere is a crucial step in occupational health, toxicology, and analytical chemistry researches. Methods: A simple and efficient system was developed for preparation of standard test atmosphere for application in occupational and environmental exposure studies, especially passive sampler's validation. Results: The system applicability was tested in various temperature, humidity, and velocity conditions. Results showed that for testing the adsorbent samplers, the system should be in hybrid mode of dilution. Conclusion: The repeatability of the measurements in the proposed system was also examined that was in acceptable range. With double dilution system it is possible to produce concentrations less than part per million.
