Volatile organic compounds (VOCs) are primarily monitored using canisters in accordance with US EPA Method TO-15. However, analysis of these ‘air toxics’ is challenged by the ever-greater range of analytes and concentrations of interest, and by the...
Markes International has produced an application note that provides an overview of the fundamentals of thermal desorption (TD) and compatible sampling techniques, as used for chemical ecology studies.
Markes International has produced an application note for the highly efficient monitoring of VOCs in stack emissions using sorbent tubes analysed by TD–GC–MS in accordance with European standard method CEN/TS 13649. The value of repeat analysis for...
SepSolve Analytical has produced an application note describing a flow-modulated GC×GC–FID system for the analysis of total petrochemical hydrocarbons (TPH) in environmental media. The application note demonstrates how use of this system eliminates...
Markes International has produced an application note describing the GC–MS analysis of humidified canister ‘air toxics’ samples at various relative humidities, using cryogen-free systems for thermal desorption preconcentration. Detection of 65...
