➢
Processed raw files are replaced by the newly generated Stats file in the Currently Loaded
list.
Viewing the Results of Raw Data Processing
Ensure that the Stats files of interest are loaded into the Currently Loaded files list.
Aggregate Data View: Generating the CSD
➢
Select a plot mode from the QuickView Processed Data frame:
❖
“Single” –
Display results from only the selected Stats file in the Currently Loaded
file list.
❖
“Multi” –
Display results from all Stats files in the Currently Loaded file list
separately on the same plot.
❖
“Combined” –
Combine results from all Stats files in the Currently Loaded file list
as if they derived from a single long acquisition.
➢
Plot the CSD using one of
two available “CSD” buttons:
❖
In the QuickView Processed Data frame (always visible)
❖
In the Aggregate Views frame of the Data Visualization tab.
Note: Stats Files
➢
A Stats file shares the same base filename as the raw file from which it was
generated, with an additional extension of the form _ssNN.
➢
In the extension, NN is an integer that increments each time the raw file is
processed.
➢
Stats files are saved in the same folder location as the raw file from which they
are generated.
➢
For full functionality, a Stats file should be kept in the same folder as its parent
raw file.
Concentration Spectral Density (CSD):
➢
The nCS1 is capable of very high resolution size and concentration
measurements of particles in a liquid, and is well suited for characterizing and
comparing subpopulations of particles in polydisperse mixtures.
➢
A useful quantity is therefore the concentration of particles in the sample over
a given size range, so that different size populations in a mixture can be
compared directly.
➢
The Concentration Spectral Density (CSD) is a measure of particle
concentration (particles/mL) per unit diameter (nm).
➢
The integral of a CSD over any size range yields the concentration of particles
(in units of particles/mL) in that range.
