Claim 16:
17. A method of detection, the method comprising:
transporting droplets through a droplet channel having a porous wall;
transporting dilution fluid into a shell surrounding the porous wall;
transporting the dilution fluid into the droplet channel at a controlled rate through the porous wall;
transporting the droplets from the droplet channel to a detection region that is fluidically coupled to the droplet channel; and
detecting radiation from the detection region;
wherein a frit provides the porous wall, and wherein transporting the dilution fluid into the droplet channel includes passing the dilution fluid through the porous wall of the frit within the shell; and
wherein the frit is a tubular frit, and wherein passing the dilution fluid including passing the dilution fluid through the porous wall of the tubular frit.
