Backwards chromatography with Mass Spec
I've been trying to run the FIAS analysis for three days now, the column just doesn't seem to be doing its job. I think the problem might be that I have it backwards. I believe the way the flow should be is into the large end and out the small end. This way, the front of the column will bind the most metals, then, when the flow reverses to rinse the metals off the column with dilute acid, the metals will be at the end of the column, so they come off together.
