Eta Carinae is perhaps the most massive star in the Galaxy, and strongly suspected to be a long-period (P=5.52 years) colliding wind binary. WR140 is a known long period (P=7.9 years) colliding wind binary consisting of a Wolf-Rayet star and O star companion. We have recently obtained high resolution X-ray spectra of Eta Carinae (near apastron in the putative binary orbit) and WR 140 (near periastron). We compare both spectra and find that they are consistent with X-ray emission formed in the shocked region where the wind from the primary and secondary star collide.
