A valve assembly and chuck system for a gas sampling apparatus. In one embodiment, the apparatus may comprise a valve assembly comprising a first core valve, wherein a pin of the first core valve is biased to a first closed position; a chuck system comprising a second core valve, wherein a pin of the second core valve is biased to a first closed position; and a transfer tube housed within the chuck system, wherein the transfer tube provides a means of displacing the pins of the first and second core valves to a second open position; wherein the transfer tube isolates a fluid communication path between the first and second core valves. In an alternate embodiment, the chuck system may not comprise a second core valve, and the transfer tube may isolate a fluid communication path between the first core valve and the chuck system.

A fluid sampling system having a nozzle, a fluid path configured to transfer a process fluid sample of a process fluid from a process fluid source of a lithium recovery system to the nozzle, a fluid control device along the fluid path, an identification tag reader, and a processing device. The fluid control device may operate between a closed position in which it prevents transfer of the process fluid sample and an open position in which it permits transfer of the process fluid sample into a sample container. The identification tag reader may read an identification tag associated with the sample container and output dispenser identification tag data indicative of the identification tag. The processing device may receive process sensor data indicative of properties of the process fluid, receive the dispenser identification tag data, and associate the dispenser identification tag data with the process sensor data.
