Microfluidic device with dried blood spots (Dbs) card interface

摘要

An apparatus for use in a chromatography system includes a first microfluidic substrate having a first fluidic channel. One end of the first fluidic channel terminates at a first fluidic port on a first side of the first microfluidic substrate and an opposite end of the first fluidic channel terminates at a second fluidic port on a second side of the first microfluidic substrate. A second microfluidic substrate has a second fluidic channel. One end of the second fluidic channel terminates at a first fluidic port on a first side of the second microfluidic substrate. The first side of the second microfluidic substrate abuts the second side of the first microfluidic substrate such that the fluidic port of the second microfluidic substrate aligns with one of the fluidic ports of the first microfluidic substrate and the alignment produces a fluidic path comprised of the first and second fluidic channels.
