3. Non-targeted Analysis Using an ICP-ToF

The simultaneous acquisition of the full elemental mass range makes ICP-ToF an excellent particle screening tool. In this example, elements of interest in a soil extract are automatically selected using parameters set during import. A full description of the non-target screening tool is available at Non-target Screening.

  1. Download the required data file.

    The tof_non_target Nu directory can be found in the example_3_data.zip archive.

  2. Import the sample file.

    Open the sample file to start the Data Import wizard. Select Non-target screening and enter 1000 into the Screening ppm field, this will select elements with greater than 1000 particles per million events. Press Ok to start the screening process.

  3. Verify element selection.

    Fig. 3.1 Elements selected during the screening are colour coded from black (low) to red (high) to show the relative number of detected particles.

    The non-target screening will automatically select all elements with detection counts above the given Screening ppm value, in this case Fe, La and Ce. Press Ok to import the data.
