1. A chromatography apparatus comprising:

  • a first microfluidic substrate having a first substantially enclosed fluidic channel comprising a sample preparation column, one end of the first substantially enclosed fluidic channel terminating at a first fluidic port on a first side of the first microfluidic substrate and an opposite end of the first substantially enclosed fluidic channel terminating at a second fluidic port on a second side of the first microfluidic substrate;

    a second microfluidic substrate having a second substantially enclosed fluidic channel comprising an analytical column, one end of the second substantially enclosed fluidic channel terminating at a first fluidic port on a first side of the second microfluidic substrate, anda dried blood spot (DBS) card having one or more dried blood spots, one side of the DBS card being coupled to the first side of the first microfluidic substrate such that one of the dried blood spots of the DBS card is in fluidic communication with the first fluidic port of the first microfluidic substrate;

    wherein the first side of the second microfluidic substrate abuts the second side of the first microfluidic substrate such that the first fluidic port of the second microfluidic substrate aligns with one of the second fluidic ports of the first microfluidic substrate and the alignment produces a fluidic path comprised of the first and second substantially enclosed fluidic channels.
