3.
Combine and Compare
At this point in the workflow, the Currently Loaded file list typically contains multiple Stats files
that together represent a polished analysis of the particle content of a single physical sample. The
goals of this workflow step are to:
1.
Combine the multiple Stats files into a single entity for simpler manipulation.
2.
Use the Viewer’s quantitative analysis tools to compare the measurement to others.
3.1
Combine multiple Stats files into a single Combined file
Combine Procedure
➢
Load the desired Stats files into the Currently Loaded file list.
➢
Navigate to the Data Output tab of the Spectradyne Viewer.
➢
In the Combine Data and Generate Run Report
frame, use the “All Loaded” button to
:
o
Combine all loaded Stats files into a single Combined file.
o
Generate a 1-page Run Report (Excel format) summarizing the measurement. See
page 36 for more details about the Run Report.
➢
Two new files will be generated in the location specified by the user in the export dialog
window:
o
A Combined file: F
ile name of the form, “
<prefix>_
YYYYMMDD_ccNN.h5”, where
NN is an incrementing number unique for each day.
o
A Run Report: Same file name as Combined file, with .xlsx extension.
3.2
Compare Multiple Analyses
➢
Load the analyses of interest into the Currently Loaded file list.
➢
In the QuickView Processed Data frame of the Spectradyne Viewer, select Plot Mode Multi.
➢
Use the tools in the Data Visualization and Quantification tabs of the Viewer to make
quantitative comparisons of the analyses.
➢
Scatter and CSD plots will display separate results from each loaded analysis on the same
axes, and quantitation tools will report results for each analysis separately.
Quantifying Particle Size Distributions
–
Concentration in the CSD
➢
The concentration of particles over a certain size range is readily obtained after plotting
the CSD (Figure 19):
❖
In the Quantification tab of the Viewer, select the size range of interest either
graphically or by manually entering the minimum and maximum values
❖
“Graphical”
–
Click Select and drag the mouse cursor across the CSD over the size
range of interest.
❖
“Manual”
–
Enter the desired min and max sizes and click Select
❖
Click “
Concentration
” to
report the concentration over the selected size range.
❖
The concentration measurement is displayed on the plot.
