Abstract
A procedure to verify the identity of hydraulic fluids (HF) type C and D U is described. Different gel filtration systems were tested to separate the constitutive components. After fractionation of the mixture, IR and NMR spectroscopy were tried for their suitability in verifying the identity of the different constituents. The combination of aqueous gel filtration chromatography and IR spectroscopy was found suitable to separate and identify the different components of HFC fluids. For HFD U fluids, a modified gel filtration system was used and NMR spectroscopy was necessary to give a decisive answer about their identity. (C) 1993 John Wiley and Sons, Inc.
