Webvapor atomic absorption spectrometry (CVAAS), and even by inductively coupled plasma mass spectrometry (ICP-MS), without interferences from the gold in solu-tion. Previously, ICP-MS was not used for mercury analysis because the mercury would deposit in the ICP-MS sample introduction system and be rel eased during subsequent analyses (carryover). Web7 jan. 2012 · Jan 6, 2012. #12. Jojo, some one onces said: "there's more than one way to skin a cat"! Well, there's also more than one way to recover &/or refine your gold. Mercury is one of the most hazardous of them all. The old prospectors used the mercury to "capture" the fine gold, then they had to heat it. This produces very toxic fumes that WILL kill you.
