WebEasily housed in the room controlling the gas extraction and ﬁltration, the Antaris IGS can provide measurements down to 7 mg/m3of total siloxane with an accuracy of 10%. … Siloxanes generally adopt structures expected for linked tetrahedral ("sp -like") centers. The Si−O bond length is 1.64 Å (vs Si–C distance of 1.92 Å) and the Si-O-Si angle is rather open at 142.5°. By contrast, the C−O distance in a typical dialkyl ether is much shorter at 1.414(2) Å with a more acute C−O−C angle of 111°. It can be appreciated that the siloxanes would have low barriers for rotation about the Si−O bonds as a consequence of low steric hindrance. This geometric consideration i…
