I have done a couple ICP tests over the past 6 months and noticed each time my Mag is 100 off between my Trident and my ICP tests. Has anyone else noticed this? I calibrate my Trident with every 2 month reagent change and my Trident has never read as high as 1500 but my ICP tests all come back that high. Not sure if a 100 difference is a huge issue or not, just something that caught my eye as a constant offset.
