Abstract:	The use of an optical-fibre polarimeter as a chemical sensor is demonstrated. The compound to be detected is allowed to adsorb onto a decladded 5 cm length of the fibre. The fibre is polarization maintaining with an elliptical fibre core and a D-shaped geometry. The overall retardation stability of this fibre polarimeter is ≈ 0.5 × 2π rad m−1 K−1. With this sensor adsorption processes of proteins can be followed on-line. The resulting relative phase retardations caused by the growth of a monolayer of antibodies (αhCG, αhSA) are 0.25 × 2π. For the much smaller protein hSA, this value is 0.1 × 2π
