Abstract: Provided are systems and methods for line volume calibration, and measurement of fluid samples delivered to an interrogation point. In various embodiments, a known fluid volume comprising a sample line fluid and a secondary fluid is delivered to a fluid boundary sensor. The fluid boundary sensor assists in determining the position of the boundaries between the various fluids, and the positions of these boundaries are used to determine the sample line fluid volume.

Abstract: A sampling system is provided. The sampling system includes a housing. Mounted to the housing is a Hall effect sensor. A probe configured to contact a sample is inserted into the housing. The probe includes an elongated portion and a restorative spring inserted onto the elongated portion of the probe. The restorative spring provides sufficient restorative force to return the probe to a relaxed position. The Hall effect sensor is configured to sense a field strength generated by the proximity of the restorative spring of the probe in the extended position.
