High performance liquid chromatography detection method for 9,9-bis(4-amino-3-chlorphenyl)fluorene in polyimide film

Abstract

The invention relates to the field of chromatographic analysis, particularly to a high performance liquid chromatography detection method for 9,9-bis(4amino 3chlorphenyl) fluorene in a film. Accordingto the method, water and acetonitrile are selected as mobile phases to efficiently analyze the content of 9,9-bis(4amino 3chlorphenyl) fluorene in an extraction liquid obtained through extraction pretreatment so as to determine the content of a to-be-detected substance in a film; the obtained chromatographic peak is sharp in peak pattern, good in symmetry, small in baseline fluctuation and free of drifting phenomenon; and the proper detector wavelength is selected, the obtained chromatographic peak signal intensity is proper, analysis and calculation are facilitated, errors are reduced, and the accuracy is improved. The analysis method disclosed by the invention is high in sensitivity and accuracy, low in detection limit and quantification limit, early in chromatographic peak appearance retention time, high in analysis efficiency and capable of quickly obtaining an analysis result.

Description

technical field [0001] The invention relates to the field of chromatographic analysis, in particular to a high performance liquid chromatography detection method for 9,9-bis(4-amino-3-chlorophenyl)fluorene in a polyimide film. Background technique [0002] 9,9-bis(4-amino-3-chlorophenyl)fluorene, as an important monomer raw material, is commonly used in the industry to synthesize high molecular polymers such as polyimide, polyamide and polyurethane, among which poly Imide is the most common. Polyimide has excellent thermal stability, chemical solvent resistance, good mechanical properties and electrical properties. It is mainly used in aerospace, microelectronics, machinery, automobiles, etc. in the form of films and molded parts. Modern industrial field. However, polyimide materials have excellent performance in industry, but the residual 9,9-bis(4-amino-3-chlorophenyl)fluorene will bring harm to people's health.
