The Particle Insight iPad app is designed to complement the Particle Insight analyzer, which measures particle shape, size, and concentration,
and can classify particles into classes based on that data. Scientists and process engineers are now able to view and study data
of their raw materials from anywhere in the world as soon as a result is available on their Particle Insight lab instrument.
The first step is to register a machine name and password, using the Support page at ParticleShape.com. You would then enter
that information in the Run Conditions options in the PI software. When a run finishes in the Particle Insight instrument, the results can be
uploaded automatically to your account on the website, if that option is set, or you can upload manually.
Uploaded data is kept in a secure location at the website, accessible only by the user who set up the account.
To download run data from the ParticleShape cloud, start the app in your iPhone or iPad. Go to "Online" and enter your machine name and password. A
list of runs available will appear. Click next to a run name to download it.
The startup screen lists the samples that have been downloaded and saved to the device's permanent memory. This is the Device view.
Select Online at the bottom of the view to get a list of samples that have been uploaded to your account at the Particle Cloud. You will first be
prompted for your username and password. Tap on a sample name to start the download to this device. To save the data to this device after
downloading, use "Save to device".
Returning to the Device view, select a sample name. A page of distribution histogram graphs is displayed, for all measures that were active
during the run. Scroll down to view data for all available measures.
Tap on any of the plots to see a full-screen version of the graph.
Use the Settings section to specify weighting (Number, Surface area or Volume), the cumulative line options, or the Sieve axis option, for
any of the active measures individually.
Selecting Statistics in the lower menu bar of any page will present a listing of mean, standard deviation, mode, and cumulative percentiles
for all active measures. Use the option bar at the top to switch between Number, Surface area and Volume weighting.
Returning to the Large Plot screen, the Comprehensive Statistics option will bring up a listing of additional commonly-used statistical values,
including Coefficient of Variance, Harmonic Mean and Skewness.
One unique feature of the Particle Insight app is the ability to analyze subranges of the size or shape measure. Drag your
finger over the plot to select a subrange of the histogram, and automatically the Comprehensive Statistics and the cumulative line will refresh to
give values for that subrange of the horizontal axis.
The Particle Insight software can convert size histogram data into simulated sieve results, for a subset of the available measures.
To use this option, turn "Sieve axis" on in either the
Small Plots view or in the Large Plot view > Settings. The software uses volume-weighted data for the conversion, since it is proportional to mass.
Up to three pages of individual particle thumbnails can be uploaded to the ParticleShape cloud storage, and downloaded to the Apple device App.
Here is a typical page of thumbnails for crystal-shaped particles.
The System Data page shows all the sample documentation, user comments, file information, system performance figures, and hardware settings saved during
the analysis of the sample. Data saved also includes all data stored by the 21CFR Part11 electronic signatures feature of the Particle Insight
if it was turned on during the analysis.
