Patent ID: 7259840

Claim:
A method for installing a radiant energy transmitting member in a fluid analysis apparatus for containing and analyzing a fluid sample, the method comprising the steps of: (a) providing a cell body assembly having an open bore extending at least partially therethrough, said open bore having first and second opposing open ends; (b) providing a compressible hollow ferrule having an inside diameter substantially equal to an outer diameter of said radiant energy transmitting member, and an unstressed outside diameter that is slightly larger than a first diameter dimension of said open bore; (c) mounting said ferrule about a first end of said radiant energy transmitting member; and (d) inserting a second end of said radiant energy transmitting member into said first end of said open bore to an extent wherein said ferrule is engaged therewithin, such insertion of said ferrule operably causing said ferrule to compress radially inwardly about said radiant energy transmitting member, thereby frictionally engaging and securing said radiant energy transmitting member within said open bore.
