During method development you should at least monitor isotopes 200, 201 and 202 for Hg and also check for tungsten isotopes 182, 184, 186 as these are interferents on Hg. Tungsten oxides and hydroxides make results of 200 and 202 isotopes of Hg biased high EVEN WITH CCT INTERFERENCE REMOVAL techniques. My experience is that isotope 201 for Hg works best in the presence of W when using CCT interference removal techniques. One wouldn't expect W in honey but you should still monitor your samples for its presence.

Subject: Hg in honey
I'm starting a new project looking at Hg in honey. All of the relevant literature I've been able to find, seems to treat Hg the same as the other metals. No special run conditions. I remember reading somewhere you need HCl and gold in your wash solution when running Hg due to carry over. I've never run honey or Hg before, can anyone lend some in site or point me to some papers?
