6.3 End-of-Line Particulate Filter Replacement
End of line (point of detection) particulate filters which protect the DOD64-FTIR from damage are required on
all points including points not being monitored. Table 7.1 details the type of filter required for each gas.
Filters must be replaced on a regular basis as shown in the table. Filter orientation is not critical in either
application.
IMPORTANT:
All points require filtration to prevent dust accumulation in tubing and internal damage to the
DOD64-FTIR. Dust that collects in the tubing or the internal system may cause sample loss and inaccurate
gas concentration readings.
