Summary of method:
This
method is based on the absorption
of radiation by mercury vapor
at the 253.7nm line. The mercury
is first reduced to the elemental
state using the procedure
outlined in EPA method 245.1.
Air is then bubbled through
the sample, speeding the mercury
vapor to the absorption cell.
The 253.7nm mercury line emitted
by the lamp is absorbed by
the vapor in the cell in proportion
to the mercury concentration.
The result is transmitted
to the Digital readout which
can be read directly in concentration
of mercury. The instrument
has a built-in "Peak-Picker"
which reads peak area. The
operator records this reading
before purging. The instrument
is then ready for the next
sample.
