So this is kind of a weird one. I was spaced out making internal standard right after my curve. I use scandium for my internal standard and multi element standard for the primary standard. I don't know if I accidentally poured scandium acid back into my primary standard container (I know not to pour things back in but I overpoured one of the liquids). I ran a curve, my curve is normal and my y-intercepts are 0.0. My ICV, CCV, and ICS all passed, so does that mean I don't have scandium contamination, and I'm psyching myself out?
