Abstract: A gas chromatography device for separating sample fluids from carrier fluids and analyzing the sample is configured so that it is a modular unit. This modularity enables repairs to be quickly effected on the unit and also greatly simplifies the task of accessing the components of the chromatography cartridge. The modular chromatography cartridge (10) is comprised of separation columns (25, 27, 29) for separating the sample fluid from the carrier fluid. The cartridge (10) additionally includes detectors (28) for detecting distinguishing characteristics of fluids exiting the column, and preferably includes valve assemblies (32, 34) for directing the flow of the carrier fluid and sample fluid throughout the cartridge (10) and restrictors (36) for adjusting the flow rate of the fluids as they flow through the cartridge. All of the components of the cartridge are configured upon a manifold (26). The manifold has a means for attaching the cartridge to fluid sources and support structure.
