MICROFLUIDIC DETECTION DEVICE

摘要

A microfluidic detection device for examining liquid chromatography samples, particularly samples from microcolumns (161). The sample enters and leaves a detection cell (20) through a restricted passageway (21) having an annular shape, so that the velocity of the sample is higher as it enters and as it leaves the detection cell (20). This reduces dispersion of the sample in the detection cell (20).
