FTIR Manual
1.4 Sample Line & Exhaust Connections
Flow connections for sample lines and exhaust lines are installed using “quick
-
connect” ports
on the inlet
manifolds and right-side panel of the DOD64-FTIR. Sample ports are labeled by number, from 1 to 64
depending on your specific instrument configuration. Exhaust ports are located on the right-side panel of the
DOD64-FTIR and are also labeled. Each sample line should be extended a maximum of 400 ft. and each
exhaust line should be extended a maximum of 25 ft.
IMPORTANT
: Be sure to exhaust system to an appropriate scrubber vent as all samples drawn from location
exhaust here at the systems exhaust ports. If gas is present at the locations monitored it will be transported
to this area so be sure to place the exhaust appropriately.
1.5 Electrical Connections
Knock out panels for external electrical connections are provided on the right-side panel of the DOD64-FTIR
(See installation Package). The DOD64-FTIR can be purchased with a side mounted power switch or internal
hard wire option with A/C filter.
1.6 Spectra and Event/Trend File
The DOD64-FTIR stores both Spectra and Event/Trend history to an external solid-state hard drive. All files
are transferable to a USB memory stick. A periodic process should be set up to remove this data from the
system to avoid memory capacity issues. Trend/Event files will be saved as .CVS files and can easily be
opened in common programs such as Excel. The Spectra files are saved in .LAB format or .SPC depending on
the interferometer type purchased with the DOD64-FTIR. The files can be viewed on an external PC using the
DOD spectra viewer. Spectra data stored in .LAB format can also be converted.SPC format, which is
compatible with other spectra open source viewers. Contact DOD Technologies for further information on
Spectra Format and viewers. All historical Spectra and Event/Trend files can be retrieved locally on the
system if needed. (Section 5.2.3)
