Hardware for an automated liquid chromatography system

Abstract

The development of laboratory chromatography requires access to tools specially designed for this selective separation technique. This paper details the design process of a multi-task programmable automaton prototype, dedicated to all types of laboratory low-pressure chromatography. This modular system, with flood gates and a command console, ensures total fluid management by surveying all the usual parameters, such as pH, ionic strength, and optical density. Real-time knowledge of the values of the flow rate and the pressure ensures total safety for materials and experiments. This “push-button type of device has its own internal data processing and graphic LCD display capabilities for fast data acquisition.
