Confidently Perform Industrial Air Analysis for VOCs with Proven GC/MS-based Solutions

Industrial air analysis includes monitoring stationary source emissions, combustion byproducts, and waste gas for hazardous volatile organic compounds (VOCs). VOCs are important precursors for atmospheric photochemical reactions, including those that generate low-level ozone and particulate matter that can lead to poor air quality. Several national and international standard methods have been developed for air toxics and related applications, including US EPA Methods TO-15 and TO-17, China’s HJ 734, and CEN methods.

Thermal desorption (TD) is a versatile preconcentration technique that is used with gas chromatography/mass spectrometry (GC/MS) to analyze VOCs in air. By concentrating organic vapors in a sample into a very small volume of carrier gas, TD maximizes sensitivity and minimizes interferences, allowing routine targeted analyte detection at the ppb level or below. If comprehensive untargeted sample analysis is required, quadrupole time-of-flight (GC/Q-TOF) MS systems provide a solution. As a leader in environmental analysis for over 40 years, Agilent offers a range of proven GC/MS systems, columns, consumables, and service to support accurate trace-level VOCs testing in industrial air.
