EXPANDED LINEAR RANGE BY USE OF TWO FLOW CELL DETECTORS WITH LONG AND SHORT PATH

摘要

A sample detection apparatus (200) for detecting a fluidic sample flowing through a first flow cell (202) and flowing through a second flow cell (204) of a sample separation system (10), wherein the first flow cell (202) has a first path length (D) and the second flow cell (204) has a second path length (d) being smaller than the first path length (D), wherein the sample detection apparatus (200) comprises a data determining unit (206) configured for determining first data indicative of a first relation between a detection signal intensity and a concentration of the fluidic sample in the first flow cell (202), and configured for determining second data indicative of a second relation between a detection signal intensity and the concentration of the fluidic sample in the second flow cell (204), and a data combining unit (208) configured for combining the first data and the second data in accordance with a continuous weighting function to thereby derive a weighted relation between detection signal intensity and concentration of the fluidic sample so that the weighted relation continuously reduces the contribution of the first data and continuously increases the contribution of the second data with increasing concentration.
