TSP Sampling Procedures
For TSP sampling, the following changes must be made to the filter holder:

• Remove the impactor(s) from the preseparator assembly and multiple impactor adapter; remove the adapter.

• Clean the cap and preseparator assembly every 5 sampling periods, or more frequently if soiling is observed.

• 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 TSP is being sampled.
