%FLOW Sample flow rate (L/min)
The Minimum and Maximum parameters define the range for each
condition during which sampling should take place.
No conditional sampling takes place if the value of all three Condition
parameters is “------.”
With the values entered in the Advanced Filter Setup screen, sampling on
will begin any time after midnight on July 24, 1998, when the ambient
temperature is between 25 °C and 55 °C and the relative humidity is
between 40% and 85%. The Sampler will continue to flow ambient air
through the sampling filter as long as both conditions are met. The
Sampler will stop the flow through the filter at any time that either
condition is not met. The Sampler will cycle the ambient air flow through
the filter On and Off for the duration of the sampling run depending upon
the ambient conditions. The filter will be exchanged at the programmed
Stop Sample time regardless of the sampling conditions at that moment.
The filter also will be exchanged regardless of the sampling conditions that
occurred during the last programmed sampling duration.
It is possible that a filter will not have ambient air flowing through it at all
during its programmed sampling duration. If the sampling conditions are
not met during a programmed sampling duration, and the filter does not
have any ambient air flowing through it, the filter will still be exchanged at
the programmed Stop Sample time.
This parameter allows the user to identify the filter type. The default for
this parameter is “P” (EPA Filter). The user can select another alphabetic
character to identify another filter type as the default filter.
The default flow rate parameter determines the sample flow rate
(volumetric L/min).
For the Partisol 2000
i
Sampler, the flow rate is typically 16.7 L/min.
The Partisol 2000
i
-D Sampler uses two flow controllers to maintain the
flow through the fine and coarse channels of the sampler. For the Sampler
to operate properly and collect PM
2.5
and PM
coarse
, the flows are set to 15
L/min for the fine flow (Flow) and 1.67 L/min for the coarse flow (Flow2).
