    Abstract: Disclosed herein are a system and method for determining a liquid level in a container based on data extracted from a digital image of the container. An image capture apparatus captures an image of a container used to store liquid reagents used by analytical instruments to test patient samples. A controller receives the captured image and extracts an analysis region based on a container type and applies a gradient filter to the analysis region. A location of a minimum gradient value (i.e., a row index) is determined based on the air-to-liquid boundary of the liquid in the extracted analysis region. A volume module calculates the liquid level in the analysis region by dividing the row index by a length of a gradient column vector and compares the determined liquid level to a threshold analysis region fraction for the container type to determine whether to output an alert.

    Abstract: Valves, pumps, detectors, sample loops, fraction collectors and the like are individually incorporated into modules that are mountable in interchangeable manner at individual mounting sites on a base unit which also supports one or more chromatography columns. Each module includes fluid connections to other modules and a microcontroller joining the module to a computed and monitor through an electronic connector at each mounting site. The fluid connections between the modules and the column(s) are removed from the electronic connections and accessible to the user. A software platform recognizes the modules and their locations, coordinates fluid connections between the modules, and provides a variety of control, monitoring, data generating and data processing functions to generate chromatographic data.
