Gold (Au)

Silver (Ag)

Platinum (Pt)

Palladium (Pd)

Iridium (Ir)

Rhodium (Rh)

Rubidium (Rb)

Zirconium (Zr)

Iron (Fe)

Nickel (Ni)

Copper (Cu)

Zinc (Zn)

Manganese (Mn)

Chromium (Cr)

Strontium (Sr)

Tin (Sn)

Mercury (Hg)

Lead (Pb)

Arsenic (As)

Selenium (Se)

Molybdenum (Mo)

Cadmium (Cd)

Barium (Ba)

Sample Types & Preparation

We can analyze alloys, beads or buttons, dore bars, liquids, powders, slurries, soils, and almost anything else. XRF analysis requires relatively small sample sizes and is not sample destructive. Samples should typically be mailed in clear sealed plastic bags (Ziploc type baggies are preferred). Most samples should be able to provide enough surface area cover a US nickel ($.05) coin when laying flat, however, some samples of much smaller sizes can be successfully analyzed but not always.

Costs Per Sample

Rapid Processing:
$45 per sample. Note: If a sample is received early enough on a particular business day it will be processed by the next business day. Business day is referring to the specific calendar day and not a particular time. We strive to deliver reports during business hours on the day the samples are due to be processed, however, this is not always possible and so reports may be sent electronically late at night. If samples are delayed in their delivery, for instance being delivered by the carrier in the evening, next business day service may not be possible in every instance. If a sample is very time sensitive arrangements should be made before your sample is shipped to ensure the most rapid turnaround and in some instances same day processing can be arranged if we are aware of your needs and when the sample will be arriving.
 
Standard Processing:
$25 per sample. Note: Reports may show a date on the sample as having been analyzed significantly before the date of report, or a report that is dated significantly before it is sent. This is due to the fact that samples will be processed when it is most convenient and then  time will be taken to analyze the data put the report together and sent to you at a different time.
