ChemStore spooler – Managing
data transfer from Agilent
ChemStation to Agilent
ChemStore C/S
To ensure optimum performance
of the Agilent ChemStation, a
background spooler takes care of
a secure result transfer from the
Agilent ChemStation data into the
Agilent ChemStore C/S database.
This approach has several advan-
tages, including
• releasing the Agilent Chem-
Station to go on with other
tasks quickly while the transfer
continues in the background
and
• guarding against data loss in
case the database insert opera-
tion fails or the network is
down.
From database to the
Agilent ChemStation
Runs which require further rework
or further investigation can be
transferred from the database to
the Agilent ChemStation.
Agilent ChemStore C/S creates an
Agilent ChemStation batch to
ensure a consistent ease of opera-
tion. The setup for this batch
resubmittal is a two-step
approach:
1. Create the batch request from
the Agilent ChemStore C/S
review client by marking the
runs for transfer in the user
interface. The operator config-
ures the transfer details in an
interactive pop-up window
(figure 4). These include
• assigning the run data to one
or, in case of several runs, to
more than one user for reanaly-
sis on a per run basis,
• optionally transferring the
method with the data (includ-
ing the choice between all ver-
sions of the method), and
• entering a comment with each
run transfer that will be dis-
played to the Agilent
ChemStation operator.
2. Use the Agilent ChemStation
Load Batch from ChemStore
menu point to select the
desired batch from the pool of
Agilent ChemStore C/S batches
to download the runs to the
Agilent ChemStation.
2. Task flow in the review
client
Retrieve and review sample
data
The task flow of Agilent
ChemStore C/S is designed to sup-
port the laboratory’s workflow
and can be outlined as follows:
1. Select the database that
contains the data you want to
work with.
2. Extract the set of results you
will work with. This is done via
a database query and the
results become the “current set
of data”.
3. Perform any of the following
tasks, in any order:
• Review the results “by sample”
or “by compound”. While
reviewing the results, you may
switch between any of several
different data presentations
(for example, a table, a chart,
or plots of the chromatograms
and/or spectra). In addition,
you may specify additional sta-
tistical computations to be
done on the results and includ-
ed in the tabular or graphical
presentations.
• Generate a report on the
data in the set of data. Any of a
set of report templates may be
used, and you may customize
those templates according to
your needs.
• Export selected data. Data may
be sent to an Excel 5.0 “*.xls”
file or to an application that
supports cut-and-paste of the
appropriate format.
• Set up a “batch” by marking
runs whose data and method
are to be transferred back to
the Agilent ChemStation for re-
analysis.
• Filter or exclude any run in the
current data set.
• Approve or reject runs based
on your result review. Both
steps follow the FDA require-
ments for electronic signatures.
