  • High-pressure cross-polar microscopy cells having adjustable fluid passage and methods of use
    Patent number: 7593101
    Abstract: 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.
