Cap the cup.
Place a label on the cup. Using a pen with indelible ink, write identifying
information on the cup. Keep a record of the sample designation, the site
and location, the date of the sample, and any other relevant comments.
Cup is ready for testing.
Sludge
Liquids
Fill an XRF sample cup with the liquid to be tested (do not pad the sample
with cotton). The cup must be full so it is best if some liquid is allowed to
overflow when the cap is put on.
Sludge Sludge can be placed directly into an XRF cup for screening. This is
considered in-situ testing because no attempt has been made to prepare the
sample. For more accuracy, the sludge can be dried, sieved, and ground.
Prepare in an XRF sample cup and test the same way you would with a soil
sample. For risk analysis, it is advisable to use a 60-mesh sieve to isolate and
test only fine particles.
