1. A system, comprising:
a phase behavior analysis unit, comprising:
a housing;
a heating system connected to the housing and arranged to heat an interior of the housing;
a pressurizing system connected to the housing and arranged to pressurize the interior of the housing;
a pressure cell positioned in the interior of the housing; and
a three-way valve comprising one inlet fluidly connected to a chamber in the pressure cell via a fluid connection and two outlets,
wherein the three-way valve and the fluid connection between the chamber and the three-way valve are positioned in the interior of the housing;
a gas chromatograph that is fluidly coupled to the chamber in the pressure cell via the three-way valve; and
a computer system operatively connected to the heating system and the pressurizing system, the computer system comprising a processor and instructions for operating the phase behavior analysis unit, wherein the instructions comprise:
applying a temperature and a pressure in the chamber of the pressure cell, wherein the pressure ranges between 5,000 and 7,000 psi; and
maintaining the temperature and the pressure within the interior of the housing, such that the three-way valve and the fluid connection between the chamber and the three-way valve are under the temperature and the pressure of the chamber.
