Abstract
Various embodiments are generally directed to techniques for monitoring chromatographic fluid flows, such as the flow to and/or from one or more reservoirs used in chromatographic operations, for instance. In many embodiments, the chromatographic operations may include one or more of High Performance Liquid Chromatography (HPLC), Ultra Performance Liquid Chromatography (UPLC), Ultra Performance Convergence Chromatography (UPC2), and the like. Several embodiments are particularly directed to a chromatographic fluid flow device (CFFD) for monitoring a change in density of a chromatographic fluid in a tube, such as by detecting the presence or absence of gas in the tube with an ultrasonic bubble detector. In various embodiments, the chromatographic fluid may include a solvent, a sample, or waste associated with a chromatographic operation.
