FIELD: physics.
SUBSTANCE: spectrophotometric liquid cell has a housing with a measurement flow channel having inlets and outlets for eluent and for optical radiation during photometric analysis of substance, made in form of a nickel capillary with a polished inner surface for multiple reflection of optical radiation, to which faces of optical guides of fibre-optic connectors are pressed.
EFFECT: invention increases sensitivity and reliability of the cell.
