~ an Advanced Laboratory Imaging and Analysis System ~

Before ALIAS, industry had to measure particles with calipers, a manually intensive task. Now there's a better alternative! Labor-saving and state-of-the-art, ALIAS uses a high-resolution flatbed scanner to optically scan, measure, and characterize large samples of particles. Developed in cooperation with CRI International Inc., the industry leader in catalyst technology, ALIAS can triple productivity while achieving high accuracy and decreasing measurement variability from site-to-site and person-to-person.

ALIAS is in use in dozens of plants and labs around the world. Currently in its seventh major release, ALIAS has been relied upon for more than twenty years by companies who value accuracy, repeatability, and dependability.


  • Scans hundreds of particles at a time
  • Three times faster than calipers
  • Maintains high accuracy
  • Fully customizable reports
  • Easy to setup and use



    If you're using calipers to measure particles, ALIAS can boost your throughput and revolutionize your characterization capabilities. Typically, ALIAS is used in a lab or plant environment where the size and shape of particles are a performance or quality control benchmark. While ALIAS is primarily designed to measure the physical dimensions and curvature of particles, it also provides data needed to compute additional properties, such as particle volume and density.


    To measure a sample, simply sprinkle the particles on the scanner, separate them, and click the mouse. Then examine the displayed results to ensure that all has proceeded as expected.


    Analysis Tools

    ALIAS provides both standard and weighted statistical measures such as sample average, standard deviation, median, kurtosis, and skewness. It also generates fully customizable histograms for any of the measured parameters. With ALIAS, several samples can be compared at once and subsets of samples can be separated for analysis.

    Sample Review

    The operator can zoom in on, swap the dimensions of, and remove any particle desired.


    ALIAS provides standard report formats that are fully customizable. ALIAS can also export its data directly to Microsoft Excel and to ASCII text files.


    ALIAS measures the length and diameter of particles as if it were using virtual calipers. It handles even curved and jagged particles, measuring them from tip to tip. ALIAS also provides additional data that calipers can not provide, such as the curvature and the area of each particle.

    Current Version
    ALIAS is currently available in version 3.7, and runs on Windows 10 (64-bit). It comes with a computer and a calibrated Epson Perfection V800 Photo scanner. If you would like information on upgrading to the latest version, with support for spherical catalysts and with other improved algorithms, please send an e-mail to Sales at ALIASCDS.com.(The latest version of ALIAS is version 3.7 and runs on Windows 10 (64-bit). It requires the latest hardware key to run: version RIMWX.)

    Here is the latest ALIAS Help file with the latest instructions for the proper use of the ALIAS system. ALIAS users should have read this ALIAS Help file, especially the sections on "General Information", "Scanning", "Saved Files", and "Verification, Self-Test and Color Calibration". This Help file explains all of the commands and options, and provides necessary training to operate ALIAS quickly, accurately, and to its fullest potential.

    ALIAS users should periodically check this site and download the most recent version of the ALIAS Help file, for the statements and operating guidance in the most recent version of the Help file take precedence over the version of the Help file that shipped with their ALIAS system.

    ALIAS Help File
    Important: To use this Help file after you download it into your ALIAS directory, open Microsoft Explorer, navigate to the file, right click on it, choose Properties, and check the Unblock box, and click OK. (If you fail to Unblock it, all of the pages will appear blank.)

    Cascade Data Systems recommends these to all ALIAS units to which they are applicable.

    Update for ALIAS Versions with Epson Perfection V700 and V800 Photo Scanners
    This update will adjust your ALIAS settings to improve the ALIAS algorithm for selecting which dimension is the diameter of a particle. (Details are in the ALIAS Help File linked above.)
    To install it, unzip this file into your ALIAS directory (typically C:\ALIAS\), and execute it when ALIAS isn't running, and click the large button.
    ALIAS Update
    (This update is unnecessary for units with the Epson Perfection V800 Photo Scanner if you install the upgrade to version below.)

    Upgrade for ALIAS Versions with the Epson Perfection V800 Photo Scanner
    This upgrade will give users the most up-to-date version of ALIAS, version Among other things, it adds a new "Values" page that makes it easier to cut-and-paste data from ALIAS to other programs.

    If you currently have ALIAS version 3.7, then you need this file:
    ALIAS Upgrade from 3.7
    If you currently have ALIAS version 3.6, then you need this file:
    ALIAS Upgrade from 3.6
    Find your ALIAS version number by running ALIAS and clicking on Help | About... in the menu bar.

    Download the .zip file into your ALIAS directory and follow the simple included instructions for copying the files over.
    Do not attempt to apply this upgrade to ALIAS units that shipped with an Epson Perfection V700 Photo scanner. It will not work with those systems because your HASP hardware key is incompatible with it, and will likely prevent your ALIAS unit from functioning.
