PM2.5 Sampling Procedures
sampling the following changes must be made to the filter holder:
Ensure that the
multiple impactor adapter with the PM10 impactor (silver)
is installed on top of the preseparator assembly, while the PM2.5
impactor (gold) is installed in the preseparator assembly.
Clean and lubricate the EMT (Easy Maintenance Target) every 5 sampling periods. The EMT may need to be cleaned more or less frequently depending on the degree of soiling.
After the sampler has been assembled, calibrated, verified to be in proper working order, and a filter loaded in the filter holder assembly, set flow rate adjustment in accordance with procedures as shown in the Operation Manual.
- Follow all other procedures in the Operation Manual, noting that PM2.5 is being sampled rather than PM10 and TSP.
