Exhaust gas collection system for supercritical fluid chromatography |
摘要 |
An efficient and safe method and apparatus for collecting exhaust gasses in an open-air sample collection container in a supercritical fluid chromatography system is claimed. The invention uses a vacuum force to evacuate the gaseous phase and vapors separated from liquid mobile phase in a sample collection device. The invention is portable to use on a series of collection containers, such as test tubes or wells in a titration place. Embodiments are claimed for capture of gasses and vapors either internally or externally to a collection container. The invention removes the gasses from the collection container that are then safely vented to a waste collector, thereby creating a safer environment for the laboratory and properly removing and disposing potentially hazardous chemicals instead of venting these chemicals into the environment.
