ABSTRACT:
A method of manufacturing a flow cell with a cell housing having a bore for the passage of sample, and with an inner layer of a totally reflecting polymer material for guiding radiation through the bore for the analysis of the sample, comprises the steps of: a) providing a tube of the polymer material in the bore of the cell housing, and b) applying a force on the walls of the tube from the interior of the tube for pressing the walls of the tube against the cell housing. The force may be applied by any suitable means, for example by drawing a mandrel through the interior of the tube, or by using pressurized gas or liquid. The resulting flow cell has a smooth inner surface with improved optical properties.
