Abstract
A capillary flow cell in which a capillary (9) partially extends along the optical path of the cell and has its two end portions (12, 13) bent to achieve an essentially Z-shaped configuration. A template (1) has a central bore (2) in which the middle part (11) of the capillary (9) is positioned. A method of manufacture of this capillary flow cell including inserting a capillary in a central bore of a template, heating the capillary immediately outside the bore to soften the capillary material, and bending the two ends to achieve an essentially Z-shaped or U-shaped configuration.
