Handheld XRF Analysis on Magnetite Fe% Variance Between Wet and Dry Sample (No replies)

I'm using a handheld XRF device for random field analysis in my magnetite plant.

I take a wet magnetite sample from my feed to plant and get a Fe% of 58.72 % but when I let the same sample dry and I measure the Fe% with the same handheld XRF device, I get a Fe% result of 61.79 %. I've done more than one test and the dry magnetite sample is on average 2 % higher than the wet magnetite sample.

Why would there be a Fe% increase on the same material with the only difference being the moisture content? 

Any help would be much appreciated.
