Option 2: Parallel Gravimetric Calibration
When the user has two sets of gravimetric sampling devices, the
D
USTTRAK™ DRX monitor advanced calibration can be performed in the
parallel configuration as shown in Figure B-1b. The calibration steps are
outlined below:
1. Install a PM
2.5
and a PM
10
impactor at the inlet of the two external
gravimetric filters, respectively.
2. Co-locate and run the gravimetric samples and D
USTTRAK™ DRX
monitor simultaneously to collect enough mass on the gravimetric
filters.
3. Calculate the PM
2.5
(PM
2.5_Grav
) and PM
10
(PM
10_Grav
) mass
concentrations from the gravimetric filters based on the net mass
collected on the filter, sampling time, flow rate, and total liters of air
sampled.
4. Read the D
USTTRAK™ DRX monitor average PM
2.5
and PM
10
mass
concentration (PM
2.5_DRX
and PM
10_DRX
) from the DRX screen or
through T
RAKPRO™ Data Analysis Software.
