• Analyzers incorporating manifolds, Chemcassette and no filters
• Flow controlling manual needle valve
• Top exhaust port
There are 72 inlets, one for each monitored location. One exhaust port is also located on top of
the Vertex Edge cabinet.
Chemcassette Detection System
The Chemcassette Analyzer module is a self-contained, microprocessor-controlled analyzer that
occupies one slot in a Vertex Edge tier. Sample lines and the vacuum source are connected to
the Chemcassette via a single 9-tube connector to develop a better stain for better sensitivity
and reliability.
The system powers up in the same state as when powered down. Data is stored in the module's
memory until the data acquisition computer retrieves it.
The Vertex Edge Analyzer modules use the Honeywell Analytics Chemcassette optical detection
system. Analyzer modules sample and detect a specific gas or family of gases.
Each eight-point Analyzer module manages Chemcassette tape transport, provides optical
detection of stain, directs sample flow through the Chemcassette to develop a better stain for
better sensitivity and reliability, and stores event data for retrieval by the data acquisition
computer.
Components of the detection system include:
• Chemcassette detection tape
• Optics and electronics for the detection system
• Chemcassette tape transport mechanism
• Manual adjustment needle valve
Detector Optics
The heart of the Chemcassette module is an optical detection system that measures a stain that
develops on the Chemcassette tape in the presence of a target gas. Each eight-point Analyzer
module has two detection heads, each with four individual detectors.
