3MTM Organic Vapor Monitors are
simple to use, but they do have
limitations just like all types of
sampling devices. Therefore, prior
to using the monitor, the user mustunderstand the limitations of this
sampling device. Accurate results
can be obtained if they are used
within their performance limitations
and if the analytical laboratory
conducting the analysis can accurately
provide correct information. Some
of the more common sampling
errors are overloading the sorbent
pad, sampling for contaminants that
cannot be captured and retained by
carbon, and the laboratory using
incorrect recovery coefficients. It is
vital that the organic vapor monitor
be used within its performance
limits and the analytical laboratory
has experience in analyzing organic
vapor industrial hygiene samples.
