Claim Text:
1. A cuvette with a rectangular cross section for use with a light scattering detector comprising: a. a sample reservoir connected to and extending upwards from a sample measurement chamber into which a liquid sample is injected, said sample measurement chamber having the shape of a right rectangular prism; b. a moat encircling said sample reservoir into which a second liquid is injected, where said second liquid within said moat is not in liquid contact with said liquid sample contained within said sample reservoir and said sample measurement chamber, wherein, further, a liquid/air interface of said liquid sample in said sample reservoir and measurement chamber is in gaseous contact with a liquid/air interface of said second liquid contained within said moat; c. a cap element sealing the opening of said cuvette from the atmosphere outside of the cuvette; d. an optically transparent surface through which a beam may pass into said sample measurement chamber; and e. at least one additional optically transparent surface through which light scattered from said liquid sample light may pass.
