The chapter focuses on vapor phase analysis techniques, particularly for monitoring air quality in conjunction with particulate matter. It highlights the importance of sampling methods, including grab sampling and absorption techniques, underscoring challenges such as concentration sensitivity and potential losses during sample collection. Additionally, it discusses various equipment used in vapor sampling and the interplay between vapor and particulate assessments.
Vapor phase analysis requires techniques that can distinguish between vapors and particulate matter.
Grab sampling is effective only when concentrations are high enough to allow for direct measurement.
Absorbents are crucial for collecting vapor samples when concentrations are low, allowing for subsequent analysis.
A technique for collecting a volume of air or vapor in a container for immediate analysis.
A material used to trap vapor components from air samples for further chemical analysis.
Methods used to assess the concentration and composition of vapor substances in the atmosphere.
