CARTRIDGE FOR A FLUID SAMPLE ANALYSER

摘要

A cartridge is used in apparatus for analysing a sample comprising a flui d and has a sample receiving cell which receives the fluid for analysis. The cell comprises a surface on one of two housing parts (120; 200; 300; 102; 2 02; 302) and a sensor comprising an electrical- mechanical transducer (92; 2 40; 340) spaced from said surface. The sensor is attached to one of the hous ing parts by an adhesive membrane (100; 246; 346) wherein the membrane is at tached only to one of said parts of housing so that any slight relative move ment or flexing of the housing parts does not result in forces being applied to the sensor via the membrane.
