Automated liquid handling and computer controlled system and method for solid phase chromatographic extractions |
摘要 |
A method and apparatus for solid phase extraction chromatography is disclosed in which the flow rate of a fluid, such as the motive pressurized gas is monitored, adjusted and compared with a standardized pressure curve which is correlative of a sample being processed. By monitoring and adjusting changes in flow rate, which can correspond to process initialization, beginning, ending and key fractionating points, and correlating to a standard, the cycle time for assaying the sample in question can be maximized and multiple samples can pass through analysis automatically and quickly.
