Abstract:
A microcrystal detection apparatus comprising:a transparent flow channel; a first polarizing means for polarizing light into a first plane of polarization; a second polarizing means for polarizing light into a second plane of polarization; said second plane of polarization being rotated relative to said first plane of polarization; a detection means for detecting a component of an associated interrogating light beam passing through said first polarizing means, said flow channel and said second polarizing means; and a cradle adapted for attaching said flow channel thereto, for aligning said light beam, said flow channel, and said detection means, whereby a birefringent crystalline material in an associated fluid flowing through said flow channel causes said light beam to include said light beam component, thereby allowing said light beam component to impinge said detection means and signal the presence of said birefringent crystalline material.
