Environmental Analysis

Thermal extraction of polymers and other vehicle interior materials followed by GC/MS analysis is a popular and useful technique for screening materials for potential emissions, from fogging of windshields to vehicle interior air quality (VIAQ)...

Analysis times for semivolatile compounds can limit sample throughput and decrease overall lab productivity. In this technical article, an example of scaling down EPA Method 8270 and using a GC Accelerator kit to reduce cycle time is presented....

This study describes the performance features that enable Markes’ thermal desorption (TD) systems to be used for the GC–MS analysis of trace-level polychlorinated biphenyls (PCBs) in air.

This study investigates the ability of Markes’ thermal desorption (TD) systems to monitor semi-volatile organic compounds (SVOCs), using a wide range of n-alkanes (n-C₁₆ to n-C₄₄) as a model. 

Markes International has produced an application note describing how a canister autosampler (using innovative cryogen-free water-removal technology) and thermal desorption–gas chromatography–mass spectrometry (TD–GC–MS) together allow the...
