Integrated instrument for supercritical fluid sample extraction, sample separation and concentration

摘要: An integrated sample extraction and separation system includes a number of substantially identical supercritical fluid modules connected in common to source modifier instruments for analysis. Each the columns is provided with separate pressure temperature controls. Preferably, each module provides choice by dissolving extracted solvent, adsorption, or size exclusion chromatography. Either various solvents may be used as mobile phase step.
