Abstract: Systems and methods are described for heating sample transfer lines between a source of a sample and a detection system to detect analytes of interest in the sample, where the sample is maintained in a heated state to maintain dissolved analytes of interest in solution.

Abstract: Systems and methods are described to provide speciation of silicon species present in a remote sample for analysis. A method embodiment includes, but is not limited to, receiving a fluid sample containing inorganic silicon in the presence of bound silicon from a remote sampling system via a fluid transfer line; transferring the fluid sample to an inline chromatographic separation system; separating the inorganic silicon from the bound silicon via the inline chromatographic separation system; transferring the separated inorganic silicon and bound silicon to a silicon detector in fluid communication with the inline chromatographic separation system; and determining an amount of one or more of the inorganic silicon or the bound silicon in the fluid sample via the silicon detector.
