1. A method for measuring UV absorption of a sample along an optical path using a Gamma radiation sterilized flow cell wherein the flow cell comprises a polypropylene material with the optical path passing at least a portion of the polypropylene material during the measurement, the method comprising:
- sterilizing the flow cell with Gamma radiation;
conveying the sample through the flow cell; and
determining the UV absorption of the sample by transmitting UV light along the optional path through the polypropylene material and through the sample.

Abstract
The present invention relates to a flow cell (10) comprising a fluid inlet (16) and a fluid outlet (18) separated by a sample flow-through chamber (12) comprising at least one UV-transparent window (22′), wherein the at least one UV-transparent window (22′) is made of a polymer material and has been subjected to Gamma radiation sterilisation. In one aspect, the flow cell is combustible.
