Patent ID: 7894071

Claim:
A measurement chip ( 1 ) for carrying out measurements of at least one of transmission, emission and scattering of light from a fluid sample in an operator unit, wherein the measurement chip has a base plate ( 2 ) produced from a transparent polymer material, at least one measurement cell ( 3 ) for receiving the fluid sample and fluid passages ( 4 , 4 ′) for supplying and discharging fluid to and from the measurement cell ( 3 ) provided in the base plate ( 2 ), and the base plate ( 2 ) has at least two mirror surfaces ( 5 , 5 ′), outside the measurement cell ( 3 ), which are arranged so that they direct the light from the fluid sample in the measurement cell ( 3 ) from the measurement chip in the direction of a light detector ( 13 ) provided in an operator unit.
