Application No. 09/746,361
fluid conduit for use in analyzing DNA and protein samples. The
fluid conduit consists of an optical analysis chamber (figure 4)
having an optically transmissive elongate tubular capillary body
(30) with an elongate tubular capillary body wall (32). The body
wall (32) includes an interior surface (36) and an exterior
surface (34), whereby the interior surface of the capillary body
wall (36) defines an elongate separation chamber, bore or sample
passageway (38) for containing the sample material being
analyzed. The body wall (32) also includes a first optically
transmissive window (40) having a substantially convex exterior
surface portion through which optical radiation passes. The
window also has a non-uniform thickness about the separation
chamber in such a way to optimize the optical coupling for
analyzing the sample material.
Claim 1 is representative of the claimed invention and is
reproduced as follows:
1. An optical analysis chamber, comprising:
An optically transmissive elongate tubular body having
an elongate tubular body wall including an interior surface and
an exterior surface, said interior surface of said body wall
defining an elongate separation chamber that is in direct contact
with a sample material being analyzed;
wherein said body wall further includes a first optically
transmissive window, said window having a substantially convex
exterior surface portion, through which optical radiation passes,
said window having a non-uniform thickness about the separation
chamber selected so as to optimize optical coupling therewith for
analyzing said sample material.
