Analytical Modules
This section describes repair procedures for the Analytical Modules for
the Modular Oven. The Maxum Modular Oven configuration is designed
for ease of repair. The primary aspect of this design is the removable
Analytical Module. This design allows the operator to quickly remove the
analytics package which is secured with only one or two bolts. The
module can then be taken back to a central location for troubleshooting
and repair. In addition, if available, the user may install a spare that is
equipped with the same hardware and columns. This allows the analyzer
to be down for a minimal amount of time while the original analytical
module is repaired (either by the customer or by Siemens).
Description
As part of the quick repair design concept, the analytical modules are
designed to be removed from the oven while the analyzer is powered up.
Analytical Modules for the Maxum Modular Oven are equipped with
Model 50 valves, columns, tubing, and either one or two center posts
that are equipped with TCD beads. These components comprise the
needed hardware for a fully functioning chromatographic application. The
components are mounted and plumbed on a manifold that interfaces to a
manifold within the modular oven of the Maxum II.

Construction
Two primary types of Analytical Modules exist, the single module and the
double module (see figure below). The single module has a single post
mounted on a small manifold. The double module has two posts
mounted on a larger manifold. When installed, both are encased in an
aluminum cover.

Multiple configurations are possible for each type Analytical Module. The
configuration for a particular customer module, including plumbing
diagrams, will be detailed in the custom documentation supplied with the
analyzer.
The analytical module plumbing interfaces to the modular oven through
the equipped manifolds. There are two oven manifold configurations,
large and small. The plumbing of the manifolds and connections for
these two configurations is detailed in the following drawings.
