Add Elements to the Worksheet

There are several ways to add an element to the worksheet:

To add elements using the periodic table:

This procedure will add an element with the default wavelength to the worksheet.

  1. Click File > New from the menu line or New > Quantitative from the Start page.
  2. If you are using IECs, choose Enable IEC on the Configuration page.
  3. Click Elements.
  4. Press the CTRL key and single-click the required element on the periodic table to add the primary wavelength to the to the element table.

Blue highlighted elements on the periodic table have been selected. Gray and blue highlighted elements are available for selection. Elements that are greyed out are not available for use.

To add elements from the drop-down list:

This procedure will add an element with the default wavelength to the worksheet.

  1. Click File > New from the menu line or New > Quantitative from the Start page.
  2. If you are using IECs, choose Enable IEC on the Configuration page.
  3. Click Elements.
  4. Click the down arrow next to the element name, and then choose the element you would like to analyze or type in the element name or chemical symbol.
  5. Click the 'Add as Analyte' button to add the selected element to the element table.

Tip
To delete elements from the element table, right-click the element and then select 'Remove'.

To add wavelengths to an element:

This procedure will add an element with the selected wavelengths to the worksheet.

  1. Click File > New from the menu line or New > Quantitative from the Start page.
  2. If you are using IECs, choose Enable IEC on the Configuration page.
  3. Click Elements.
  4. Click the required element on the periodic table.
  5. Select the wavelength from the wavelength table to the right of the periodic table.
  6. Click Add.

Tip
You can press CTRL and select multiple elements to add at the same time to the element table.

To manually enter or change a wavelength:

This procedure will change the wavelength of an added element in the element table. If the wavelength of interest is not listed, manually enter your required wavelength. The manually entered wavelength needs to be within the wavelength range of the instrument.

  1. Click File > New from the menu line or New > Quantitative from the Start page.
  2. If you are using IECs, choose Enable IEC on the Configuration page.
  3. Click Elements.
  4. Click the wavelength of the element of interest in the element table.
  5. Type or select the new wavelength.

The instrument will automatically monitor the detector at the added wavelength.

This does not amend the wavelength database. This new wavelength will have to be typed into every method.


Set Up a Method that Contains Internal Standards

You select internal standard lines in ICP Expert in exactly the same way as you do analyte lines, from the Element page of the worksheet.

The Internal Standard column appears after you have chosen 'Internal Standard' as the element type. Once this column appears, all analyte lines will have a drop-down option and show the currently selected internal standard. Elements selected as an internal standard will not have a drop-down menu available in the Internal Standard column.

Tell me more about Internal Standards.

To add and link an internal standard:

  1. From the Element page, select an element and then click Add. The element will appear in the element table.
  2. In the Wavelength field, select the wavelength you require from the drop-down list.
  3. In the Type field, select Internal Standard from the drop-down list.
  4. Click the Internal Standard cell of the Analyte of interest and select an Internal Standard line from the drop-down list.
  5. Once you have linked an analyte line to an internal standard line, the ICP Expert software will automatically apply the appropriate correction factor to the analyte line during the analysis.

Assign Interferents

  1. Click File > New from the menu line or New > Quantitative from the Start page.
  2. Choose Enable IEC on the Configuration page.
  3. Click Elements.
  4. In the Type field, select Interferent from the drop-down list.

Click here for more information about how to Setup and run a method with IEC.

To duplicate wavelengths as interferent lines:

  1. Click File > Open from the menu line or Open from the Start page and then choose an existing worksheet with IEC enabled.
  2. Click Elements.
  3. Right-click the wavelength of interest in the element table.
  4. Select Duplicate as Interferent line.

This procedure is useful when an analyte for one sample acts as an interferent for another sample. The analyte can be added as an interferent using existing spectra data after obtaining results. 

View Possible Interferences

The Possible Interferences table shows the possible interferences that could occur in your analysis for the element currently selected in the element table.  Elements that have been classified as Analytes, Internal Standards or Interferents will be highlighted in the Possible Interferents table.

  1. Click File > New from the menu line or New > Quantitative from the Start page.
  2. If you are using IECs, choose Enable IEC on the Configuration page.
  3. Click Elements.
  4. Click the wavelength of the element of interest in the element table.
  5. The currently selected element is highlighted in blue in the table. Any other elements selected in the worksheet are highlighted in red.

Click the graph icon to display a graphical representation of the possible interferences. Zoom in on the graph by left-clicking on the graph 'X' axis and moving the cursor left to right. You can then left-click the graph and drag the graph to the left or right. The selected element will have a green pointer. Click the table icon to display the interferences table.
