| 摘要 |
A system for colorimetric titration, comprising a container (10); a mixing device (11), which is arranged to extend along a substantial portion of a longitudinal axis of the container (10); and an analysis arrangement (12) having a housing in the form of a collar which is adapted to fit around and at least partially enclose, a section of said container extending in a plane substantially perpendicular to the longitudinal axis of the container and not intersected by the mixing device (11) in the container (10). The collar houses at least one electromagnetic radiation source, arranged to emit electromagnetic radiation towards said container (10); and at least one electromagnetic radiation detector, arranged to detect electromagnetic radiation, emitted from the at least one electromagnetic radiation source through the container (10).
