Method for cleaning flowpath components of fluid flowpath of analysis device e.g. liquid chromatography apparatus, involves pressurizing flowpath components of fluid flowpath of analysis device with liquid carbon dioxide

摘要

The method (100) involves pressurizing (102) flowpath components (206,208,210,212,214,215,217) of a fluid flowpath (202) of an analysis device (200) with liquid carbon dioxide. The flowpath components are purged (104) with a solvent based on pressurization process. The flowpath components are purged (106) with liquid carbon dioxide.
