Abstract: A system includes an analysis system at a first location and one or more remote sampling systems at a second location remote from the first location. A sampling system can be configured to receive a remote liquid sample. The system also includes a sample transfer line configured to transport gas from the second location to the first location. The sample transfer line is configured to selectively couple with a remote sampling system for supplying a continuous liquid sample segment to the sample transfer line. The system can further include a sample receiving line at the first location. The sample receiving line is configured to selectively couple with the sample transfer line and the analysis system to receive the continuous liquid sample segment and supply the sample to an analysis device.

Abstract: Systems and methods are described to determine whether a sample transmitted through a transfer line from a remote sampling system contains a suitable sample to analyze by an analysis system. A system embodiment includes, but is not limited to, a sample receiving line configured to receive a liquid segment a first detector configured to detect the liquid segment at a first location in the sample receiving line; a second detector configured to detect the liquid segment at a second location in the sample receiving line downstream from the first location; and a controller configured to register a continuous liquid segment in the sample receiving line when the first detector and the second detector match detection states prior to the controller registering a change of state of the first detector.
