    摘要: A two-beam spectrophotometer comprising a monochromator and a beam splitter is provided. In addition to being inclined to the optical axis by an angle .alpha./2 lying in the optical plane, the beam splitter is inclined to the direction perpendicular to the optical plane, so that the reference beam is deflected out of the optical plane by an angle .beta.. This improves the spectral intensity distribution.A spectrophotometric method employing this apparatus is also provided.

    摘要: A flow cell for high performance chromatography, in which the measuring chamber is formed by a bore (12) in a plate (11) and the supply and discharge ducts are formed by bores (13, 14) in the plate (11) communicating with grooves (16, 18) in the plate surfaces (15, 17), the grooves being covered by transparent plates (19, 20) bonded on the plate surfaces, and thus forming closed ducts.
