In some polymers, in addition to the usual structural alpha relaxation, a slower alpha' relaxation is observed with a non-Arrhenius temperature dependence. In order to understand better the molecular origin of this alpha' relaxation in poly(methylphenylsiloxane) (PMPS) we have studied

Different methylphenylsilicone (MPS) and fluorosilicone (FS) oils having a higher specific gravity than water were investigated as vitreous replacements. Their intraocular tolerance in vitrectomized aphakic rabbit eyes was evaluated for periods of up to 4 months and compared to that

The supercritical fluid chromatography of intact aliphatic amines with different columns is described. One group of amines was based on N,N-dimethyl-n-octylamine and related primary and secondary amines, and the other on the amino alcohol metoprolol and several of its analogues.

The gas chromatographic-mass spectrometric (GC-MS) separation of all 209 polychlorinated biphenyl (PCB) congeners was studied on an extremely efficient 80 m x 0.1mm i.d. capillary column coated with a 0.1 microm film of poly(5%-phenyl methyl)siloxane stationary phase. The quality of

A method based on the use of absorbents as packing materials in the interface of the direct coupling between reversed phase liquid chromatography and gas chromatography (RPLC-GC) is proposed. To that end, a comparative study on different adsorbents and absorbents
