1.4 Analyzer Modules

The Vertex M System is populated with one or more
types of analyzer modules. Each system may contain
Chemcassette modules or Pyrolyzer modules.
®
Modules are installed in slots.

1.5 Sampling System

Each Analyzer module is a monitoring center for
sampling lines from sample locations. As they apply to
the Vertex M System, the words point, line and location
require definition:
• A location is a place to be monitored
CC
• Sample atmosphere runs from the location to
the Vertex M System via a line
• Each of the 24 sample tubing connections on
the Vertex M System corresponds to a point.
A sample line can be connected directly to
a single point or multiple points via a 4-port
manifold
The system draws air simultaneously from all locations.
Total Two different types of flow are:
• Transport flow: high-velocity, large-volume air
movement through the lines
• Sample flow: air admitted to the
Chemcassette
The high speed of transpor t flow allows rapid
monitoring and response time when using long lines
from monitored locations to the Vertex M System. A
small portion of the transport flow (sample flow) is
analyzed to determine concentration levels.
The complete sampling and monitoring system consists
of the following components:
• Sample lines to all monitored locations
• Flow connections through quick-connect ports
in bulkheads on top of unit
• Moving cable and connectors
• Vacuum pumps
• Analyzers incorporating manifolds,
Chemcassette
• Flow controlling proportional valve
