Abstract:
A device for feeding a chromatography flow coming from a flow source, selected from a liquid chromatography (LC) separating unit or a peak sampling or trapping unit, in part to at least a first decision detector unit and/or at least a first destination detector unit and in part to a second destination detector unit, comprising:a first capillary line coming from said flow source, a second capillary line leading to said first decision detector unit and/or to said first destination detector unit, a third capillary line leading to said second destination detector unit, a flow splitter connecting said first, second and third capillary line with one another and splitting maid flow coming form said first capillary line into two parts, a first part being fed into said second capillary line and a second part being fed into said third capillary line, a first switchable valve means connected to said third capillary line and to said second destination detector unit, wherein said first switchable valve means has at least two operating positions, wherein in at least a first operating position said third capillary line is connected directly to said second destination detector unit, and wherein in at least a second operating position said third capillary line is connected to at least one delay line.
