Automated infrared spectrometer liquid transmission cell filling and flushing device

A liquid transmission cell system comprising:

• a liquid transmission cell comprising a first and a second cell port;
• a first valve assembly having four connection positions, wherein each of the four connection positions connects, respectively, a first, second, third, and fourth connection port to a fifth connection port;
• a solvent fill tube coupled to the second connection port;
• a waste disposal tube connected to the third connection port;
• a sample fill tube coupled to the fourth connection port;
• a second valve assembly having two rotation positions and first, second, third, fourth, fifth, and sixth pairing connection ports, wherein each rotation position couples each pairing connection port with one of two adjacent pairing connection ports such that each position creates three pairs of pairing connection ports, wherein fluid passes between each pair of pairing connection ports;
• a third valve assembly having a first and a second gas connection port;
• a gas fill tube coupled to the first gas connection port;
• a pump;
• a first waste reservoir;
• wherein the first pairing connection port is coupled to the first cell port;
• wherein the second pairing connection port is coupled to the first waste reservoir;
• wherein the third pairing connection port is coupled to the second cell port;
• wherein the fourth pairing connection port is coupled to the second gas connection port;
• wherein the fifth pairing connection port is coupled to the second gas connection port;
• wherein the sixth pairing connection port is coupled to fifth connection port.
