The calculated partition coefficient from the respective ppLFER equation is only valid for aqueous concentrations in the range of 0.03 mmol/L. The GASTEC GSP series automatic gas samplers use this method. Using the indicated value (that is read) and a prescribed calculation factor the volume of the target substance contained (in the liquid sample) can then be extrapolated. With its four sampling modes, Centri offers maximum versatility for liquid, solid and gaseous samples. The compressed air is sampled by attaching a pressure reducing valve with flowmetre (between the vessel and the detector tube) in order to enable the pressurised air/gas inside the vessel to flow via the flowmetre into the detector tube at a fixed rate of flow for a predetermined time.
