Live CSD
–
Quantitative Real-time Data Analysis
A live CSD plot enables quantitative evaluation of the current run in real-time.
➢
The Live CSD feature displays a combined size distribution from the current cartridge run.
➢
The Live CSD is updated each time a new stats file is generated by the auto-analysis engine.
➢
Display Options (see Figure 13. Auto-analysis Engine Interface.):
o
“ON” –
Control display of the Live CSD.
o
“Log Y” –
Plot the y-axis in log scale to view concentrations over multiple orders
of magnitude in a single sample.
o
“Show History” –
Display all acquisitions that are included in the combined
distribution.
o
“Auto
-
filter” –
Apply default peak filters to stats files at the time of processing. It is
recommended to always leave this on. The original data is still available for regular
post-processing in Viewer if desired.
NOTE: When a combined file is created
from the engine (see below), the default filters will be applied and saved with
the file if the checkbox is marked at the time of saving.
o
“Reset Data” –
Clear the history of acquisitions displayed in the Live CSD.
➢
Concentration Measurements on the Live CSD:
o
Specify an integration range using the
“Measure Size Range”
box entries provided
and click “
Set
”
.
o
The measured concentration for a specific size range (with statistical error) is
displayed.
➢
Automatically Stop Data Acquisition by Particle Count or Concentration Error Limit:
o
Specify a size
range using the “Measure Size Range” entries and click “Set”
o
Check the
“Set Acquisition Stop Point”
box
to activate the “Percent Error” and
“Number of Particles” entries
o
Specify a stop point by the statistical error on the integrated concentration or by
the number of particles
o
Data acquisition will stop once the specified limit has been reached
o
NOTE: The End Run routine must be performed to prepare the cartridge for
removal
➢
Create a Combined File and 1-page Run Report:
o
“Combine Data and Create Run Report” –
Create a combined file and generate a
Run Report (see page 36) for the acquisitions displayed in the Live CSD for the
current measurement run.
NOTE:
Default filters will be saved with the resulting
file if the “Auto
-
filter” checkbox is on.
➢
Which data is included in the Live CSD?
o
All data from the current cartridge run and
since the ‘Reset Data’ button was last
pressed.
o
No peak filtering is applied if the
‘
Auto-
filter’ box is not checked—
false positive
detection events may be included
. For more in-depth data analysis use the Data
Viewer (page 22).
