Immission measurements with IMR-MS according to EPA methods


Several methods to measure environmental contaminants have been approved by the Environmental Protection Agency (EPA). The most commonly used are TO-14 and TO-15, where the determination of volatile organic compounds (VOCs) in ambient air is achieved by collecting samples in specially prepared containers. The samples are then analyzed using gas chromatographs (GC) or GC combined with mass spectrometers (GC/MS). The need to first take samples and then analyze them in special laboratories can significantly slow down any decisions to adjust the process if one wants to avoid potentially negative effects on the environment.


V&F offer IMR-MS instruments capable of continuous on-line measurement against an industrial background. A wide range of components can be measured simultaneously without the need for sampling or pre-concentration. Comparisons with EPA-approved technologies such as TO-14/15 show that the selectivity and sensitivity of the V&F instruments is on par with GC and GC/MS.

V&F instrumentation facilitates time-resolved analysis of contaminants in accordance with EPA-approved procedures. The compact size of the system provides flexibility in the choice of measurement locations. The instrument can be set up in a fixed location or loaded onto a small van and measurements can even be determined while driving. Since the results are transmitted directly, process changes to air pollution can be initiated immediately to protect the environment.
