Sample capture assurance for sample bottles

An arrangement for determining a state of a sample bottle, comprising:

• an external housing;
• a fluid chamber configured to hold a fluid obtained from an environment. the fluid chamber within the external housing;
• a separation piston positioned at one end of the fluid chamber, the separation piston configured to move from a first position to a second position;
• a closure device configured to establish a closure;
• a central rod positioned within the external housing, the central rod configured to interface with the separation piston and move the separation piston from the first position to the second position;
• a protrusion extending from the central rod, the protrusion extending into a flowline;
• and
• a proximity sensor located at a peripheral end of the protrusion, the proximity sensor configured to limit movement of the central rod when the proximity sensor is activated.
