Abstract
Analytical cartridges, systems and methods of processing a sample for analysis using capillary flows. Vertical gradient sample filtration provides filtrate to an incubation chamber for a time controlled by a flow modulator at the outlet of the incubation chamber. The flow modulator can include a serpentine capillary flow path without side walls. Incubated filtrate can flow from the incubation chamber to a detection channel after a predetermined time. The detection chamber can include one or more analytical regions in a porous substrate for detection of two or more analytes on the same cartridge from the same sample.
