Abstract (en)
A fluid handling method and device for use in analysing a fluid are described. The device has a sample chamber (50, 150) for retaining a predetermined amount of the fluid for analysis in the sample chamber, and a pre-chamber (20, 130). An entry (30) to the pre-chamber requires pressure to inject the fluid into the pre-chamber. A connecting passage (40, 140) from the pre-chamber to the sample chamber allow flow to the sample chamber by capillary action. This flow can be less sensitive to any variability in the injection. This means the injection pressure or duration, need not be so closely controlled. In turn this can enable simpler or more cost effective apparatus.
