Paper Abstract

A commercial interface for deposition and infrared analysis of a high temperature GPC effluent was used to characterize NBS standards and experimental polyolefins. With this commercial interface, LC-Transform (Lab Connections, Marlborough, MA), the GPC effluent is nebulized and the solvent evaporated in a heated nitrogen jet onto a rotating reflective disc. Optimization of nebulizer conditions for deposition quality and sensitivity was investigated. High sensitivity can be obtained over most of the molecular weight range allowing trends in end groups, comonomer content, and crystallizability to be observed. Novel workstation software for exploiting the information from this dynamic 3-D type of experiment is presented.
