Abstract

Columnas capilares para la separación de enantiómeros en cromatografía de gases. Las columnas constan de un tubo de sílice vítrea, vidrio (puede ser tipo borosilicato, o bien sodocálcico u otro) o algún material similar en cuanto a características de composición, inercia química, y propiedades mecánicas. El tubo de sílice vítrea va recubierto externamente de poliimida para reforzar su estabilidad a la rotura. La longitud práctica de los tubos oscila entre 10 y 50 m de longitud, pudiendo variar entre 1 m y 200 m; el diámetro interno suele variar entre 0.1 y 0.5 mm. Las etapas más novedosas del producto son el tratamiento de la superficie interna del tubo capilar y la fase mixta empleada. El objeto de esta patente es la fabricación este tipo de columnas capilares son aptas para la separación de enantiómeros por cromatografía de gases.Capillary columns for the separation of enantiomers in gas chromatography. The columns consist of a glass silica tube, glass (can be borosilicate, or sodocálcico or other) or some similar material in terms of composition characteristics, chemical inertia, and mechanical properties. The glass silica tube is coated externally with polyimide to reinforce its breakage stability. The practical length of the tubes ranges between 10 and 50 m in length, and can vary between 1 m and 200 m; The internal diameter usually varies between 0.1 and 0.5 mm. The newest stages of the product are the treatment of the inner surface of the capillary tube and the mixed phase used. The purpose of this patent is to manufacture this type of capillary columns that are suitable for the separation of enantiomers by gas chromatography.
