Abstract
Systems and methods are described to maintain a liquid sample segment of a sample transmitted through a transfer line from a remote sampling to an analysis system. A system embodiment includes, but is not limited to, a sample transfer line configured to transport a liquid sample from a remote sampling system via gas pressure; a sample loop fluidically coupled with the sample transfer line, the sample loop configured to hold a sample fluid; and a backpressure chamber fluidically coupled with a gas pressure source and with the sample transfer line, the backpressure chamber configured to supply a backpressure against the liquid sample during transport through the sample transfer line.
