XRF Procudure

Starting for the Day:

  1. Turn on laptop and XRF
  2. Connect with NDTr software
  3. Print off lab sheets from Google drive
  4. Make sure old data is cleared off (procedure below)
  5. Select Run Time and Sample Type (procedure below)
  6. Enter information into data entry tab on XRF.
  7. Start processing samples

Clearing Old Data:

  1. On XRF main menu, click on Data tab.
  2. Once opened, click on Erase tab, then click on Erase readings tab.
  3. When prompted, click yes to erase data off the XRF. (Only do this once you have exported data, otherwise sample data will be lost and will need to be rerun.)

Data Entry Tab:

  1. To access the data entry tab, in the main menu click on the Analyze tab.
  2. On the next screen click on the data entry tab.

Sample: Project area code and year sample was taken (GFS16, OSS14 etc)
Location: Project area sample was taken from (Goodfoot, Oversight etc)
Inspector:
User's initials
Once those fields have been entered, hit the green return key in the bottom left of the screen.

Filling out XRF sheets:
Sample Batch: ADZ_XRF_*projectarea*_*date*_SOILS or MINING Sample ID: GFS160123 (no hyphen for final data set.) Date: Standard YY/MM/DD Tech ID: User's initials Standards: Are run every 10 samples along with duplicates. (QA/QC Control) Duplicates: Indicate duplicates with a D at the end of the sample number (i.e. GFS160123D) Reruns: Indicate reruns with an R at the end of the sample number (i.e. GFS160123R); rerun samples with any gold or silver

Changing Run Time and Sample Type:

  1. From main menu, click on the Sample Type tab.
  2. Then click on the Soils and Minerals tab.
  3. If running Mining, click on the Mining Cu/Zn tab, if running Soils click Soils tab.
  4. Once selected you will be brought back to the data entry screen, return to the main menu.
  5. From the main menu, click on the Advanced tab.
  6. Then click on the Start/Stop Setup tab.
  7. Click on the Max. Time button on the bottom right of the screen.
  8. Hit the C button to clear out the entry field.
  9. If running on Mining: Enter 150.0 and hit E If running on Soils: Enter 90.0 and hit E
  10. Click the Save button, and on the next screen hit return and then the Analyze tab.

Sample Taking Procedures:

  1. Twist bag to remove as much air as possible, and secure with rubber band.
  2. Flatten out one part of bag so it sits flat on XRF tray.
  3. Wipe bag off before placing on XRF to reduce contamination.
  4. Make sure the sample is entirely covering the hole in the center
  5. Make sure lid is closed and locked
  6. Press start
  7. After sample is run, if there is any Au or Ag, run the sample again as a rerun (procedure above)
  8. Prepare next sample, pay attention to standards and duplicates listed on the sheet
  9. Use this time to fill out XRF sheet, including sample ID and any lab comments.
  10. When timer runs out, remove sample from XRF and start process over with a new sample.
  11. When last sample has been run, change the sample type and run time (procedure above)
  12. At the end of your shift, begin the exporting data process (procedure below)

QA/QC Control:

  1. Standards and duplicates are run every 10 samples. (Follow XRF sheet)
  2. Use air can to spray off dust before running each sample in order to reduce contamination.
  3. Make sure to wipe off bags before placing on XRF to reduce contamination.

Exporting Data:

  1. Close out of NDTr and open NDT
  2. Click download
  3. Click on test in the window that opens to see if the XRF and program are communicating. If NDT tests and is correctly communicating with the XRF, query the readings, and select all.
  4. Before downloading, rename the data to the same as on the paper printouts, ADZ_XRF_GF_170101. Put whether it is Mining or Soils, and an A or B if you have multiple runs during your shift.
  5. When the download is done, close out of the download window, and the data should pop up as a spreadsheet.
  6. Click on the tools tab, select export data. A second window will open, hit start to begin download. Once finished, hit close and exit out of the NDT program.
  7. Open the XRF_Data folder on the computer desktop and open the file folder for the location the samples came from. Then create a new folder with the date you ran the samples through the XRF.
  8. Drag the two new tabs that were created from the data export into the new folder. Scan the XRF work sheets into the computer and put the file in the folder as well.
  9. Open Google drive, under the shared with me tab, open up the XRF raw data uploads folder. Open up the folder for the location the samples came from, create a new folder with the date, and copy everything from the XRF_Data desktop folder into the Google drive folder of the same date.

Troubleshooting:

  1. If the XRF and the computer program quit communicating (screen freeze): Close the NDTr program on the computer and wait 15-20 seconds for the XRF to beep. Once you hear the beep, hit the XRF power button 4-5 times to reset the XRF without turning it off. Open the NDTr program again and see if it is communicating once again. If not repeat the above steps one more time. If it is still not communicating, close the NDTr program once more and hold down the power button on the XRF to completely turn it off. Wait 30 seconds to 1 minute, then turn the XRF back on and reopen the NDTr program.
  2. If the NDT program will not communicate, make sure the NDTr program is closed before running. If NDTr is closed, but it still will not communicate, sometimes opening the settings in download and reselecting the port will fix it. Otherwise try restarting the software or rebooting the computer.
