Abstract: A continuous, inline, flow rate measurement system for rapidly measuring a flow rate in an analytical instrument having a primary pump that outputs a primary fluid at the flow rate to be measured or verified. The flow rate measurement system includes an auxiliary pump that outputs an auxiliary fluid bubble having a detectable characteristic that is distinguishable from the primary fluid, a bubble injection system that injects a small portion of the auxiliary fluid into the conduit, and a bubble detection system for measuring the position of the auxiliary fluid bubble as a function of time based on a time of detecting the detectable characteristic of the auxiliary fluid, and a controller for converting the measured position of the auxiliary fluid bubble as a function of time into a volumetric flow rate based on a known volume of the conduit.

Abstract: A standardization device for calibrating a spectroscopic apparatus. The spectroscopic apparatus includes a light source, an optical device to be standardized, and a sensor. The standardization device includes an optical standardization device, an adaptor, and an optical fiber. The optical standardization device transmits at least one monochromatic light beam. The adaptor is removable disposed within the spectroscopic apparatus and interposed between the optical device to be standardized and the optical standardization device. The adaptor transmits the monochromatic light beam between the optical standardization device and the optical device to be standardized. One end of the optical fiber is connected to the standardization device while the other end is connected to the adaptor. The optical fiber transmits the monochromatic light beam between the optical standardization device and the adaptor.
