Assay Reports for Different Industries
Do you know what Assay to look for and how to read it?
Different industries have slightly different assay's, but in general, an assay is :
"An assay is an investigative (analytic) procedure in laboratory medicine, pharmacology, environmental biology and molecular biology for qualitatively assessing or quantitatively measuring the presence, amount, or functional activity of a target entity (the analyte)."
Why would you want to know more about an assay? Great question! How do you know what someone is selling you is what they say it is? Is it the correct concentration? Does it have the correct chemical makeup? An assay will tell you all this and more.

Please keep in mind that precious metals also can have an assay. Some of the techniques used to assay precious metals are:
Fire Assay – Fire assay is one of the oldest methods of checking the purity of content in precious metals. Gold and silver are both checked this way, with corresponding amounts of silver and gold used together in a cupel, or disposable crucible, which helps check the amount of non-precious or impure metals in a sample.
Dry Assaying – Dry assaying works for gold and silver, as well. Fluxes, which are chemical cleaning agents, get heated with the metals. This creates a combination of any impurities, and in turn, it creates a slag. During the process, the precious metals separate and the purest forms settle at the bottom. After the mixture cools down, the slag gets chipped away, leaving the metal to get weighed and compared.
Wet Assaying – In wet assaying, solvents dissolve the sample. This process leaves a solution that the assayer analyzes chemically. Depending on the metal or ore in question, assayers can use salts or electrolysis to separate it.
Spectrograph Assaying
Spectrographic assaying requires the sample to actually emit light. This occurs when the assayer passes electrical discharge through the sample. Assayers look at the intensity and strength of the light emitted by the sample, allowing them to measure the sample’s metal content.
X-Ray Fluorescence Assaying – In X-ray fluorescence assaying, the metal actually emits X-rays. This requires irradiation by an X-ray beam. The assayer judges the metal depending on the intensity level of the X-rays it emits.
Other Assaying Methods – Typically, titration is the process used to assay silver. Cupellation is the process used to assay gold. With platinum, ICP OES, or inductively coupled plasma optical emission spectrometry, is the process used to test purity.
In closing, If you are dealing with anyone who is dealing in Precious metals or Fuel/Oil, they should be more than familiar with the need for an assay.
