Installing and Using Column ID Tags
Using Column ID Tags
The Agilent InfinityLab Column Identification Tag is designed to enable the
automatical detection of the columns installed in the column thermostat and
help the user to track the usage of the columns in the laboratory. The column
identification tag contains information about not only the physical properties of
the column but also about its usage. Two types of information are stored:
• Static fields contain information on the physical characteristics of the column
such as the length, internal diameter and particle size. Typically, this
information stays the same for the lifetime of the column.
• Dynamic fields contain information on the usage of the column, such as the
number of injections and maximum measured temperature. The information
stored in the dynamic fields will be automatically updated each time a new
analysis is performed with the column. These fields are read-only from the
perspective of the user, meaning that their content cannot be manually edited
or erased.
For pre-labeled Agilent columns, the static fields are pre-populated with
information and set to read-only for compliance reasons, except for the Void
Volume and Comment fields. The dynamic fields are blank by default and will be
automatically edited by the system upon using the column.
On the contrary, custom column identification tags enable the user to edit the
content for all static fields, as long as the tag is not sealed. This can be beneficial
when using non-Agilent columns. After entering all the necessary information, the
custom tag can be sealed to prevent any further modification of the content in
the static fields. The content of the dynamic fields cannot be manually edited or
erased, not even for the custom tags.
NOT E
The information in the dynamic fields cannot be erased by any means.
NOT E
When the column identification tag is sealed, the static fields will become
write-protected and only the dynamic fields will remain available for updating.
The only exceptions from this are the static fields Void Volume and Comment.
