- Primary duties are assisting as needed in the core lab and on the Core receiving platform. For details on Core lab responsibilities refer to the Core lab SOP.
- Prepare XRD, ICP, and pXRF samples for analysis.
- Read available literature to understand the theory and operation of XRD, ICP, and pXRF analysis. Be prepared to answer questions or at least point a scientist or tech in the right direction.
- Keep X-ray lab and ICP prep area clean. A high level of cleanliness must be maintained at all times during ICP preparation. Frequent vacuuming will keep dust to a minimum.
- Maintain a chronological log of lab events to assist in an accurate Technical report at the end of the expedition.
Data Curation
- Save Bruker XRD files in *. raw, *.pdf or *.png and *.uxd format. Upload the XRD files to LIMS.
- Save Aeris XRD files ??? (Aeris file saving is being discussed by Lab Working Group)
- Save pXRF files in *.csv and *.spm files. Upload XRF files to LIMS.
- Verify that all samples have been analyzed by running a LIMS Report query.
- Upload LOI Spreadsheet to LIMS.
...
- Maintain AMS inventory sheet. Do physical counts of supplies.
- If the equipment is not operating properly, learn how to fix it. Only qualified technicians should attempt to make more than minor adjustments or repairs to the D4 or handheld XRFinstruments. The Xray technician should attend the Bruker service course , Olympus and Aeris courses if available on shore to become qualified at identifying problems and trouble shooting. Communicate with vendor technicians (Bruker, Olympus Aeris) and E.T's if assistance is required.
- Monitor oil levels in vacuum pumps. Change oil regularly, and perform one full service and maintenance of pumps per expedition.
- Monitor water level in Haskris water pump. Clean or change water filter as necessary.
- Ensure desiccant in desiccators is dry and ready for use. Oven dry if necessary.
- Clean freeze-drier valves, vials, and the desiccators. Replace filters as required. Drain water from the unit and dry inside. This is performed as needed (~ once a week).
- Record and date any maintenance in the XRD maintenance log on confluence. For all correspondence with vendors, ALO and LO's concerning maintenance and repairs, CC your cross shift.
