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.

A servo-electric actuated sampler can draw samples of fuel liquid from an operating main line. The sampler can run in a fast-loop process whereby liquid is drawn into the sampling system and past an actuated sampler and then out of the system back into main. The system main run a short loop whereby the main fast-flow is restricted, and the actuator and sampler are isolated from the main line flow. When isolated, the sampler discharges liquid into sampling cans. The servo-electric actuator requires a monitored amount of power to draw and discharge fluids. Monitoring of the power requirements of the servo-electric sampler can reveal the status and reliability of the system.
