Introduction
1.1 Overview
The Model 3500 series Laser Gas Analysis System comprises a
range of instruments based on the features and configuration chosen at
the time of purchase. The system uses laser spectroscopy to accurately
measure and monitor the composition of a single or multiple gas species
in a gas mixture. It is especially useful for in-situ measurements and is
designed for online processes analysis. Options are available for
applications involving hazardous environments.
This manual describes the installation, calibration, operation, and
maintenance of the LGA system. The principles of instrument operation
are detailed in Section 2.
1.2 Models Available in the 3500 Series
The Model 3500 series of instruments are classified depending on
the options specified at the time of purchase. The specific model number
assigned is described below following a brief description of the available
options to choose from.
1.2.1 A VAILABLE O PTIONS
The standard Model 3500 LGA System is configured for single gas
species detection in a gas mixture using a flange mounted laser transmitter
and receiver for online in-situ measurements in non-hazardous environments.
The following list indicates available options for the Model 3500
series of analyzers (see also Table 1-1):
• Two gas detection in a gas mixture
• Fiber optic connection to remove sensitive laser and electronics
from monitoring environment
• Explosion-proof housing
• Intrinsically safe instrumentation
