2.9 Column Compartment

The following sections provide a brief overview of the key features of the column
compartment.

2.9.1 Gas and Humidity Sensors

A gas sensor and a humidity sensor are installed inside the column compartment. The
sensors detect any gas or humidity that may accumulate in the column chamber. You can
adjust the sensitivity of the gas sensor and the humidity sensor in Chromeleon or on the
front panel display (→ page 130).
When a certain concentration of gas or humidity is reached inside the column compartment
(while the door of the column chamber is closed), the related sensor is activated and the
Status LED on the front panel door turns red. A message appears on the front panel display
and in the Chromeleon Audit Trail. It depends on the sensor settings whether a beep sounds in
addition to alert you (→ page 130).
When a sensor reports excessive gas or humidity, find and eliminate the source for the
leakage (→ page 178).

2.9.2 Column Switching Valves

The column compartment can be equipped with one or two column switching valves
(→ page 19) and thus, provides highest flexibility for all applications that required
different columns at similar temperatures. The switching valves are installed in the column
chamber, where they are brought to the preferred temperature together with the columns.
For information about how to connect the components to the column switching valve, see
page 82.

2.9.3 Column Identification System (Column ID)

The column compartment is fitted with an electronic column identification system (column
ID) that allows you to store column-specific information on a column-ID chip card. This
information provides a GLP-compliant overview of the column status. The chip card is
connected to the column for the column life cycle. Column identification is supported for
up to four columns simultaneously.
The information on the column ID chip card is continuously updated and can be reviewed at
any time in Chromeleon, as long as the column and chip card are installed in the column
compartment. For more information about the column ID, see page 129.
