Abstract
A method of analyzing fluid samples using a bent capillary flow cell, in which method an external UV/visible light ray beam is directed into an elongated section of the flow cell from a bend thereof, this incident light ray beam is limited to a solid acceptance angle .OMEGA.. This solid acceptance angle .OMEGA. is determined such that light rays which enter the elongated section traverse predominantly the longitudinal axis thereof, i.e. propagate through the fluid sample, providing an improved S/N ratio. Lens means, such as ball lenses, may be used at the entrance and exit side of the elongated section. A bent capillary flow cell is provided, in which the elongated section deviates by an angle .psi. from a line N perpendicular to a flat side face of a holding template.
