Abstract

Apparatus (1) for metering analytes in liquid samples apt to be used in underwater environment, comprising: a sampling unit (2) to allow the addition inside the apparatus itself of the liquid sample (C) to be analyzed; a unit (22) for the addition to the sample of reagents (R1, ..., Rn); a unit (28) for detecting the concentration of the analytes contained in the sample; a closed circuit (10) which connects the above mentioned units to allow the continuous and repeated circulation of the sample among them; and a peristaltic pump (29) arranged along the closed circuit, the arrangement being so that the reagent-inletting valves of the addition units are arranged along the closed circuit, implementing tracts with tortuous development of the latter and so that the mixing between sample and reagents takes place thanks to the turbulent motion which begins during the circulation of the sample inside the circuit.
