Identify and Analyze Particles
Use the advanced particle analysis tools to locate, characterize, and identify particles.
The particle selection tools are available only with the optional Particle Analysis Add-On.
Begin particle analysis with either a video image of your sample or with a chemical image.
Collecting a chemical image before performing particle analysis allows you more options to
analyze your sample but data collection takes longer.
Video Image-Based Particle Analysis
Use the particle selection tools in the Acquisition window to automatically detect and select
particles in your sample. Collect single point spectra or regions for each particle. After
measuring the particles, view particle properties such as size, quantity, and type in the results
table in the Analysis window.
To detect and measure particles using a video image
1.
onto the microscope stage.
2.
.
3. Click the
Video
button in the software to select video mode.
4.
Bring the sample into focus and collect a mosaic
5. Use
Live spectrum mode
to acquire spectra at several locations of the sample in order to
optimize the
settings.
6. Click
Image Regions
to select image regions mode.
7. Select the
Auto Regions
tool (
) and navigate to the
Particle Selection
tab.
The currently selected particles are displayed in the mosaic pane. Use the particle
selection tools to refine the selection. See
Settings for Particle Analysis
for details.
8. When you are satisfied with the selection, click
Keep Regions
.
You can add or remove regions and points manually before collecting data.ffg
9. When you are ready to collect the image data, click
Collect Regions
.
The collected data appear the Analysis window.
For more on exploring your results, see
View Particle Analysis Results
. You can refine your
results by using the
Search Setup t
ools to specify one or more regions to use in the spectral
search.
