Abstract: Various implementations include a system and methods for capture and transfer of a liquid sample from a process to a sample analysis device. In particular, a sample of fluid can be contained in a non-pressurized line and first and second air-operated valves may prevent the fluid from flowing through the line. A third air-operated valve may be positioned on a stub-out of the non-pressurized line between the first and second air-operated valves. A sample line, also configured to contain a sample of the fluid, can extend between the third air-operated valve and a sample analysis device to transfer the sample of fluid to the sample analysis device. A first pneumatic valve can control air flow to the first and second air-operated valves; a second pneumatic valve can control air flow to the third air-operated valve; and a third pneumatic valve can control low-pressure air injected into the sample line.
