Abstract: The invention is about a chemical analysis apparatus (100), comprising a liquid flow train assembly for creating a flowing liquid sample stream guided from a sample inlet (22) through the apparatus (100) in a capillary tubing arrangement at low liquid flow rates, the sample containing an analyte to be measured, the apparatus further comprising reagents dosing and injection means, located downstream the sample inlet (22), for introducing a series of chemical reagents into the sample stream, the apparatus further comprising reactor means (4) where the reagents are reacting with the analyte for producing a coloured chemical indicator in the fully reacted sample, the apparatus further comprising detection means (1) for measuring the chemical indicator, said detection means (1) being located downstream the reactor means (4) and being configured to receive the fully reacted sample with the coloured indicator from the reactor means (1). The flow train assembly is configured to intermittently let the fully reacted sample pass through the detection means (1) at times when the measurement of the indicator is not made, and to bypass the detection means (1) at times when the measurement of the chemical indicator in the sample contained within the detection means is made.
