1. A system for sum frequency generation spectroscopy, the system comprising:
a pressure cell comprising:
a metal pressure chamber including:
a liquid sample holder that retains a liquid sample;
a removable lid that seals against a base to enclose the liquid sample holder in an interior of the metal pressure chamber;
a window in the removable lid that allows the liquid sample to be optically accessed from an exterior of the metal pressure chamber;
a sample inlet that flows the liquid sample from the exterior of the metal pressure chamber to the liquid sample holder in the interior of the metal pressure chamber at a predetermined flow rate; and
a sample outlet that flows the liquid sample from the liquid sample holder to the exterior of the metal pressure chamber;
a heating stage, disposed in the interior of the metal pressure chamber, that heats the liquid sample;
an ultrasonic stage, disposed in the interior of the metal pressure chamber, that emulsifies the liquid sample;
a chamber pump, connected to the interior of the metal pressure chamber, that pressurizes the interior of the metal pressure chamber; and
a controller that controls the chamber pump, the ultrasonic stage, and the heating stage to control a pressure of the interior of the metal pressure chamber, an emulsification of the liquid sample, and a temperature of the liquid sample, respectively; and
a sum frequency generation microscope comprising:
a first light source that generates light of a first variable frequency;
a second light source that generates light of a second frequency; and
a detector that detects light.
