Interferences For So Measurements - Teledyne 100E Instruction Manual

Model 100E Instruction Manual Getting Started
3.3.2. Interferences for SO
Measurements
2
It should be noted that the fluorescence method for detecting SO is subject to
2
interference from a number of sources. The most common source of interference is from
other gases that fluoresce in a similar fashion to SO when exposed to UV Light such as
2
nitrogen oxide (NO) and poly-nuclear aromatics (PNA), of which certain hydrocarbons
such as meta-xylene and naphthalene are the most pervasive. The M100E has been
successfully tested for its ability to reject interference from most of these sources.
For a more detailed discussion of this topic, see Section 10.2.6.
NOTE
Once you have completed the above set-up procedures, please fill out the quality
questionnaire that was shipped with your unit and return it to T-API. This
information is vital to our efforts in continuously improving our service and our
