28 Understanding Your Agilent ChemStation
1 Agilent ChemStation Features
About the ChemStation Software
The partial sequence functionality allows users to see the order of execution of
the sequence and also select individual sample entries to rerun or re-evaluate.
When re-evaluating data already acquired users can specify whether
reprocessing uses the original sample quantification data or new data entered
in the sequence’s sample table.
Sequences may be paused to run single injection priority samples by another
method, then restarted without disrupting the automation. Samples can be
added to the sequence table while the sequence is executing.
Both the sequence and partial sequence tables may be printed.
For more information on sequences, see “Automation” on page 159, and the
online help system.
Good Laboratory Practice
The ChemStation is developed to internationally recognized design and
development standards and has a number of features specifically to help users
operating in a regulated environment. These features are in the area of
complete method specification and verification that the methods are fit for
their intended use, to check the operation of their system and ensure the
traceability, originality and quality of the data.
Development Process
The Certificate of Validation shipped with each software package documents
the software development and testing steps executed as part of the
development cycle. The development process is registered to the ISO 9001
quality standard. It is documented together with onsite revalidation protocols
in the Validation BinderAgilent ChemStation for LC.
Method Specification and Use
• Global methods — the complete instrument and data analysis specification
is stored in one place. Methods include individual compound range
specifications to check that quantification results are not applied outside
the calibrated range.
