- Check water level and temperature of Haskris chiller. Ensure filter is clean.
- Before running the Bruker D4, initialize the sample changer from XRD Commander Program or if from a complete shutdown initialize sample changer first using D4 tools, then initialize using Commander, then run 'tube conditioning program in D4 Tools. (Instructions are in the XRD Bruker Manual).
- Run QAQC Standard in Bruker D4 as detailed in manual.
- Coordinate a work area in the fume hood with the chem tech and make sure there is a 10% Nitric bath available for cleaning quartz and platinum crucibles.
- Familiarize yourself with the expedition prospectus and ascertain a likely number of ICP, XRD, and pXRF samples that can be processed. Discuss sampling with Curator and applicable scientists. The core lab is your primary duty and x-ray must come secondary to that unless arrangements are made with the Lab Officer to meet specific objectives. Scientists should be made aware of this and that it is not reasonable to expect high resolution on a high recovery expedition.
- Provide training to scientists on using XRD software (EVA and Highscore)
- Provide training to scientists on hand held XRF in instrument operation, sample preparation, and data upload/download procedure
- Provide XRF safety training to scientists who uses hand held XRF. Check out and assign dosimeter ring to individual scientist. Ensure they understand all safety concern and sign required document.

- 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.
