Powder X-ray Line Diffraction Study on Mono Sodium L-glutamate Pentahydrate by Whole Powder Pattern Fitting Analysis

The crystallographic bibliography of mono Sodium L-glutamate Pentahydrate (MSLGPH) found unique unparalleled structural geometry using powder X-ray diffraction (XRD). The XRD analysis revealed the atomic structure of MSLGPH crystals providing a detailed refinement of lattice parameters and crystal symmetry. Crystallography revealed dislocation density of 2.009 × 10⁻⁴ nm⁻², crystallinity index of 1.98, unit cell density of 1.48 g/cm³ and specific surface area of 57.46 m²/g, contributing to unique structural geometry. Rietveld refinement confirmed a unified 100.0 % crystalline phase using the WPPF method. The calculated lattice parameters are a= 6.224, b= 16.669, c= 5.992 Å; α= 98.77, β= 99.83, γ= 98.54° in a triclinic crystal system with lattice volume of 595.565 ų and strain of 0.163 %. The strongest diffraction distinct 2θ at 20.364° (0-31) plane. Various models were used to estimate crystallite size, with the Scherrer equation exploring an average crystallite size of 70.55 nm for nano confirmation.
