sample submittal formYes, Rakita is using Au-ICP21 indeed. I was actually just worried because you used AA26 in the past but if you are following Rakita protocol Au-ICP21 is the method. I was actually not concerned about upper detection limit but lower. If you expect 1-2ppm of Au you could also use AA gold. The lab where we do Au is in Romania, very close to us at they are very fast in getting the results fast. In LR where we do ICP gold and multielement analysis it can get busy and results are sometimes delayed. If the lower detection limit is not a problem for you I would suggest you use AA gold. We will do whatever you decide. Thank you once more.
