Appendix A
Interference Table
Refer to Table 4 to match the interfering gas symbol with the gas name. Then refer to Table 5. The Cross
Interference Table extends for 5 pages, with each sensor specific gas repeated in each section of the table, for a
column listing of 40 gasses. The list is followed by a row of 14 possible interfering gasses per page. Review
each page for the applicable sensor gas and then scan across the row for possible interference gasses.
