AUTOMATED SAMPLING AND REACTION SYSTEM FOR HIGH PRESSURE LIQUID CHROMATOGRAPHY AND OTHER TYPES OF DETECTION

摘要

PROBLEM TO BE SOLVED: To provide a system, method, and apparatus for automated sample preparation and sample reaction.SOLUTION: An automated sampling and reaction system and a method of using the same are provided. The automated sampling and reaction system has a microreactor in fluidic communication with an external sampling valve. The external sampling valve is connected to a priming valve and can be configured to draw a sample from a reactor or a reactor stream. The microreactor is connected to a reagent valve and an injection valve. The reagent valve can be configured to draw a reagent from a reagent reservoir and discharge the reagent to the microreactor to react with the sample. The priming valve can be configured to draw a wash from a wash reservoir and discharge the wash to the external sampling valve to move the sample from the external sampling valve to the microreactor. The injection valve is in fluidic communication with a column or a detector and discharges a secondary sample into a solvent composition stream.SELECTED DRAWING: Figure 1
