Apparatus and methods are described for observing samples at non-ambient temperatures and pressures. One apparatus comprises a cell body having a fluid flow-through passage and a light passage intersecting the fluid flow-through passage at an adjustable light pathlength fluid analysis region; first and second light-transmissive windows in the light passage, each window having at least one crystal axis aligned longitudinally with a longitudinal axis of the window, the windows having opposed, spaced apart, substantially flat surfaces defining the adjustable light pathlength fluid analysis region, the first window having a first window holder and the second window having a second window holder, the first window rotationally isolated from the first window holder, the second window rotationally coupled to the second window holder, the first window holder able to gradually move the first window and thus adjust the light pathlength; and first and second light polarization filters.

High-pressure cross-polar microscopy cells having adjustable fluid passage and methods of use

A fluid analysis assembly for analyzing a fluid the fluid analysis assembly includes a chamber, a fluid movement device, a pressurization assembly and at least one sensor. The chamber defines an evaluation cavity for receiving the fluid. The fluid movement device has a force medium applying force to the fluid to cause the fluid to move within the cavity. The pressurization assembly changes the pressure of the fluid in a continuous manner. The at least one sensor communicates with the fluid for sensing at least one parameter of the fluid while the pressure of the fluid is changing in the continuous manner.
