Liquid cell for spectroscopic analysis
First Claim
1. A liquid cell for use in spectroscopic analysis of flowing liquids formed by a front plate as an optical window, a back plate having spaced apart apertures therein, a tapered reflecting surface on the back plate between the apertures, and a sealing means between said two plates, each of said apertures being an entry and an exit port, respectively, for liquids to the cell.

Abstract
A liquid cell for use in spectroscopic analysis of flowing liquids formed by a front plate (1) as an optical window, a back plate (2) providing a reflecting surface (6), and a sealing means (3) between the two plates. In the back plate there are entry part (4) and exit part (5) for liquids to the cell. This arrangement is convenient to connect for liquid through-put, and gives extra sensitivity and allows detection of very small quantities of material present in the flow.
