So I confess I am a little puzzled by this one. I have had three triton tests come back with excessively high tin since December. The first one was over 100. Each one, has been a little less than the last though. After the first one, I thought I'd try a different brand test to compare results. This test has come back twice now showing little or no tin at all. One (the second I sent in) got lost in the mail and still hasn't shown up. So three tritons show tin near 100, and two of the Icp-anaylsis tests show tin at .009 Anyway I'm just really wondering how their can be such a massive discrepancy between the two. Anyone else have super inconsistent results like this between different tests?
