The purpose of this research was to quantify the magnetooptical properties of monosodium urate (MSU) crystals that would allow for an easy diagnosis using a magneto-optical device (MOD). Characterization of these magnetic and optical properties was achieved by measuring the transmitted light intensity of a laser shining through a sample of monosodium urate with or without an applied (static) magnetic field. Using our theoretical model under the simplifying assumption that absorption is dominant, we determined that the extinction cross-section is σ𝑥 = 0.0127 cm3 /μg and we determined σ𝑧 using two different relationships which gave two distinctly different values. Due to this 78.8% difference in our calculations of σ𝑧 , we determined that the extinction cross section for MSU crystals relies on both scattering and absorption interactions.
