Patent ID: 7808619

Claim:
A method for securely installing a radiant energy guiding member within a fluid analysis cell body, the installation method comprising: (a) providing said cell body with an open chamber extending therethrough, said open chamber being defined by a chamber wall, and having a first open end, a second open end, and a central axis extending therebetween; (b) providing a compression sleeve member in the form of a resilient tube having an unstressed outer diameter slightly larger than a first diameter dimension of said open chamber, and an inner diameter that is substantially equal to, but slightly larger than an outer diameter of said radiant energy guiding member; (c) inserting said radiant energy guiding member into a channel defined by said compression sleeve member; (d) drawing the combination of said compression sleeve member and said radiant energy guiding member into said open chamber, such drawing operably elongating and radially constricting said compression sleeve member about said radiant energy guiding member, thereby frictionally engaging and securing said compression sleeve member and said radiant energy guiding member to one another; and (e) allowing the combination of said compression sleeve member and said radiant energy guiding member to relax and expand within said open chamber, such expansion frictionally engaging and securing said compression sleeve member to said cell body.
