(a) Raman calibration standards for β-L-glutamic acid aqueous slurries showing the concentration dependence of the 865.97 cm−1 peak of the solid-state spectra with increasing slurry mass. (b) Magnification of the dotted box in (a) showing that the LOD for the β phase of L-glutamic acid slurries is ∼0.1 wt%. (c) Linear calibration curve for the peak height and integrated peak area of the 865.97 cm−1 peak. (d) Interval plots of the peak heights for the 0.5 and 1.0 wt% L-glutamic acid slurries, showing the spread of data for five replicates used to calculate the standard deviation and RSD.
