<p>An analysis apparatus (1) for analysing fluid is disclosed. The apparatus (1) comprises a fluid communication system (3) connected to a fluid medium (7), having a first pressure, P1, via a connector (5). The apparatus (1) further comprises at least one reagent container (8) comprising a first volume (10a) and a second volume (10c). The first volume (10a) contains reagent and is fluidly connected to a detection unit having a second pressure, P2. The second volume (10c) is fluidly connected to the fluid communication system (3), and therefore has pressure P1. The second pressure is lower than the first pressure, P21, and the reagent container (8) is arranged to deliver reagent in response to this pressure difference. The pressure difference also drives the collection of sample fluid (11), and thereby the ratio of sample fluid (11) and reagent reaching a detection unit (9, 19) is independent of fluctuations in one or both of the pressures, P1 and P2.</p> |
