USER PERFORMANCE VERIFICATION

INTRODUCTION

Performance verification can be done by introducing a pure sample of the compound
through a septum into a closed loop circulating pump which is connected to the analyzer.
The closed loop calibration system, consisting of the septum, pump, and tubing is
available from Thermo Fisher Scientific.

PROCEDURE

Warning: Intrinsically safe models require special actions with respect to the following
section. Refer to Appendix C for descriptions of these actions.
1. Before connecting the closed loop calibration system to the analyzer, it must be
free of all contaminants. Therefore, zero the analyzer (see Chapter 5, "To Zero the
Analyzer"). When display says to install the particulate filter, go to next step of
this procedure instead.
2. Connect tubing from the OUT connector of the closed loop pump to the IN port
on the analyzer. Also connect tubing from the IN connector of the closed loop
pump to the OUT port of the analyzer (see Figure 12-1).
