Abstract:

An apparatus for analyzing a process stream (1) via supercritical fluid chromatography including container means (10), extraction means (50) for drawing a known sample volume from the process stream and injecting the sample volume into a known volume of supercritical fluid to form a dilute mix (5), analyzer means (70) for analyzing the dilute mix via supercritical fluid chromatography, sample inlet valve means (60) for receiving the dilute mix from the extraction means (50) and supplying a portion of the dilute mix to the analyzer means (70), pneumatically driven piston-type pump means (30) for drawing the substance from the container means (10) and delivering same under pressure either to the extraction means (50) or to the analyzer means (70) as desired, and control means (40) for supplying low pressure air to the pump means (30) in a controlled manner so as to draw the substance from the container means (10) and maintain the substance at a desired pressure above the supercritical pressure for delivery to the analyzer means ( 70) and the extraction means (50) as desired.
