To examine the settings of the analysis, click once on 'Handheld X-Ray Fluorescence Analysis' and then select the settings icon 
that appears. A window will appear below this icon detailing the parameters the analysis is looking for (Fig. 24). If any changes need to be made to file types or editable fields, this can be adjusted here, however, it is strongly advised to have Developer assistance. The analysis parameter 'FirstElementName' indicates that should change when uploading the element results, it will begin once it reaches the column with MgO reported. For the Geoexploration and Limestone applications, the first element reported is 'MgO'. However, for the Precious Metals 2, 'Al' is reported first and for the Mudrock applications, 'Na' is reported first. Therefore, you will need developer assistance to change this or uploading of the data will not happen properly (element results will be skipped until it reaches the column reporting 'MgO'. If an application other than GeoExploration is used, see below and consult a developer for what changes will need to be made to the analysis settings, namely 'FirstElementName'. The developer can convert 'FirstElementName' into a list of elements if other applications are used.
the 'Application' for which an upload is being conducted is changed. The 'MgO' shown here supports the GeoExploration application (and it eponymous TSV file).

Regarding the 'AddFiles' setting. This field accepts full file names. It does not accept wildcards or a bare undotted extension--for example supply "csv" will have no effect unless the file is actually named that.
Options for 'FirstElementName'.
- The 'MgO' search string is associated with the GeoExploration application. This is the most often used configuration of the Bruker device in the IODP environment.
- At this time MUT supports only one 'Application' at a time. Switching applications requires changing the search string to accommodate processing for a different application.
- Note that vendor application defaults cause the TSV file to carry the same name as the 'Application'.
- The search string is simply an aid for the software to find the first column of data to be prepared for transfer to LIMS. The software assumes all subsequent columns carry content for LIMS. While this has been tested for the output of the GeoExploration application, it has not been vetted for all the applications that the Bruker device supports.
| Search String | Application |
|---|---|
| MgO | GeoExploration Limestone |
| Al | Precious Metals 2 |
| Na | Mudrock |
If the application of interest is not listed here, conduct a test so that a TSV file is generated for the application. Open that file with a text editor. Look for the element or simple compound that identifies the first column of data. That will become the search string that MUT requires to conduct its processing for that 'Application'Figure 24.
