4 Data Acquisition
Estimate of worklist file size
Overlapped Data Analysis with Acquisition
You can choose to start the next data acquisition run when the
data analysis is complete, or for higher throughput of samples,
while data analysis of the previous sample is still running.
This option is selected in the Worklist Run Parameters dialog
box, in the Execution for Acquisition-DA list box. To overlap
data analysis with acquisition, select Asynchronous. To cause
data acquisition to wait until data analysis is complete, select
Synchronous.
Overlapped Injection
You can load a sample into the sample loop during a run that is
still completing. This option allows you to save time that is
required to load the sample before the run.
To select this option, mark the Overlapped Injection check box
in the Worklist Run Parameters. You also have to select this
option in the individual methods being used in the worklist.
Estimate of worklist file size
Depending on your estimate of the file size of the worklist, you
may have to change the default value of the Free Disk
Threshold.
You can run a typical worklist sample to estimate the worklist
file size. Then, you observe the file size in Windows Explorer,
and multiply the observed file size by the number of samples in
the worklist.
The data file for profile data is compressed by a factor of 3 - 20,
depending on the complexity of the mass spectra acquired. This
new feature greatly reduces the data storage needed for profile
data.
The Instrument Mode selected for the Accurate-Mass TOF and
Accurate-Mass Q-TOF also affects the size of the data file. The
Agilent TOF and Q-TOF instruments now will acquire 2 times as
