Abstract

A chemiluminescent detector having a first reflective layer; a second transparent layer; the first reflective layer having cut therein a first sample flow path; an exhaust flow path and a reagent flow path, said sample reagent and exhaust flow paths having at least one capillary channel joining the sample and reagent conduits such that the sample and reagent conduits can mix in the exhaust conduits at a plurality of discrete points and create a plurality of chemiluminescent reactions.

Claims

1. A chemiluminescent detector comprises:

a reflective layer;

a transparent layer,

said reflective layer having a sample conduit, exhaust conduit and reagent conduits, said sample and reagent conduits being separated by said exhaust conduit and each of said sample and reagent conduits having at least one capillary channel which enters said exhaust conduit such that the sample and reagent mix in the exhaust conduit proximate to said capillary channels and initiate a chemiluminescent reaction.

2. The chemiluminescent detector of claim 1 wherein said reflective layer comprises silicon.

3. The chemiluminescent detector of claim 1 wherein said transparent layer comprises fused silica.

4. A chemiluminescent detector comprising:

a first layer of reflective silicon;

a second layer of transparent fused silica bonded to said silicon;

a plurality of conduits embedded into said silicon, said conduits comprising a sample conduit, reagent conduit for a reagent and

an exhaust conduit interspersed between the reagent and sample conduits; and

a plurality of capillaries for joining the sample and reagent conduits with the exhaust conduit such that the reagent and sample meet a number of locations in the exhaust conduit and thereby initiate a plurality of chemiluminescent reactions.

5. The chemiluminescent detector of claim 4 wherein said detector has a circular shape.

6. The chemiluminescent detector of claim 4 wherein said sample and reagent conduits comprise interlocked fork-shaped conduit members.

7. The chemiluminescent detector of claim 4 wherein said exhaust conduit comprises a serpentine-shaped conduit which is interspersed between the prongs of the fork-shaped sample and reagent conduits.

8. A chemiluminescent detector comprising:

a first layer of silicon and second layer of fused silica, said first layer of silicon being reflective and having embedded therein;

a first fork-shaped conduit for carrying a reagent;

a second fork-shaped conduit for carrying a sample, said second fork-shaped conduit extending in a direction opposite to said first fork-shaped conduit and being offset therefrom, the branches of said first and second fork-shaped conduits being intertwined;

a serpentine exhaust conduit extending between the branches of said sample and reagent conduits; and

a plurality of capillaries which link said sample and reagent conduits with said exhaust conduit so as to provide a plurality of sites on said exhaust conduit for chemiluminescent reactions.
