Exporting Data from Malvern Zetasizer Instrument

To use the analysis script package documented here, the data collected from the Malvern Zetasizer instrument must be exported in a specified format.

Here, the format in which the data must be exported is detailed.

Setting up the export template

The data, which should be composed of one longer measurement that collects the time-averaged scattering and several shorter measurements that collect the position-dependent scattering, must be exported in a specified format, which can be made into a template to be saved in the Export Templates folder.

To do so, select all rows of the data, then go to File and then Export.... In the first tab, be sure to save the file where you want to save it and ensure that the file is a .csv file. In the second tab called Parameters, select the option Use export template parameters to export using a template and create a new one.

As previously documented (insert reference to paper), the new template should contain the following information in exactly this order:

  1. Record Number
  2. Sample Name
  3. Measurement Position
  4. Correlation Data
  5. Correlation Delay Times
  6. Distribution Fit Data
  7. Distribution Fit Delay Times
  8. Cumulants Fit
  9. Cumulants Fit Delay Times
  10. Derived Count Rate
  11. Measured Intercept
  12. Measured Size Baseline

Additionally, it is critical to NOT check the option Include Header Row, select the option Enclose text in quotation marks to keep each piece of data separated in its own column, and select Use comma as separators to allow compatibility with the analysis script method.

Give this template a name (not Microrheology because that is a default template).

Exporting the data

Once you have saved this template and selected it as the template for exporting your rows of data, click OK and you should see a new .csv file in the folder that you saved it to.

In the future, you can cut short your steps for exporting your data to:

  1. Select all rows of your data
  2. Go to File and select Export...
  3. Select the destination for your data and ensure the file is saved as a .csv file.
  4. In the second tab Parameters, select the option Use export template parameters to save the data using a template and choose the template you made above.
  5. Click OK. Your data is saved!
