9.4. PNEUMATIC OPERATION
IMPORTANT
It is important that the sample airflow system is leak-tight and not pressurized over
ambient pressure. Regular leak checks should be performed on the analyzer as described
in the maintenance schedule, Table 8-1. Procedures for correctly performing leak checks
can be found in Section 8.3.6.
IMPORTANT
Relative Pressure versus Absolute Pressure
In this manual vacuum readings are given in inches of mercury absolute pressure (in-Hg-A), i.e.
indicate an absolute pressure referenced against zero (a perfect vacuum).
9.4.1. SAMPLE GAS FLOW
The Flow of gas through the T100 UV Fluorescence SO

Analyzer is created by a small
internal pump that pulls air though the instrument.
