    摘要： A liquid analyzer comprises a liquid sample intake for immersion in a liquid sample; at least one measurement zone; and a first pump module operable to effect liquid flow from sample intake towards the at least one measurement zone. A first pressure monitor is provided to measure pressure between the sample intake and the at least one measurement zone and the operation of the first pump module to regulate the liquid flow in the liquid conduits is regulated in dependence thereon.

    摘要： A system (102) for determining properties of a sample (114) comprises a LIBS detector (104,106) and an infra-red absorption detector (108,110) for interrogating a sample (114) to generate LIBS spectral data and infra-red absorption spectral data respectively; and a data processor (112) adapted to apply at least one chemometric prediction model, each constructed to link, preferably quantitatively link, features of both LIBS and absorption spectral data to a different specific property of the sample, to a combined dataset derived from at least portions of both the LIBS and the absorption data to generate therefrom a determination, preferably a quantitative determination, of the specific property linked by that model.

    摘要： A method of performing an optical analysis of a liquid containing dissolved gas includes transferring an amount of the liquid containing the dissolved gas from a reservoir into a holder of a flow system of the optical analyser, holding the amount of the liquid in the holder at around ambient pressure for a period such that a portion of the dissolved gas is expelled from the amount of liquid held in the holder while the holder is open to a waste reservoir, transferring at least a portion of the amount of the liquid containing the dissolved gas held in the holder under a pressure above ambient into a measurement cell of the optical analyser as a liquid sample, and performing the optical analysis of the liquid sample from a detection of optical radiation by an optical detector after its interaction with the liquid sample in the measurement cell.
