Abstract:
1. A method, comprising: passing a sample across a first measurement zone of a microfluidic system; passing at least a first wash fluid and a second wash fluid across the first measurement zone; measuring light transmittance or light absorbance through at least the sample, first wash fluid, and second wash fluid at the first measurement zone; forming signals corresponding to the passing of at least the sample, first wash fluid, and second wash fluid across the first measurement zone, wherein an intensity of each signal is indicative of the fluid passing across the first measurement zone, and wherein a duration of each signal is indicative of a volume and/or flow rate of the fluid passing across the first measurement zone; and determining whether to modulate fluid flow in the microfluidic system and/or alerting a user of an abnormality in an analysis being conducted in the microfluidic system based at least in part on information derived from the intensity and/or duration of one or more signals.
