compound)
• CAS No.-Sometimes it is easier to identify a VOC from the
internationally recognized CAS (Chemical Abstracts Service)
number
• Formula-Molecular formula for each VOC
• Response Factor (RF)-The relative response factor for each gas.
This is the value that is plugged into the Eagle 2 Maintenance Data
Loader Program.
Some abbreviations that appear in the table are:
• ZR-No response
• NV-Cannot be measured
