Figure 3From: Supersaturated state of diazepam injection following dilution with infusion fluid Microscopic images (a) and FTIR spectra (b) of the precipitate and analytical-grade DZP. The region of interest for the measurement of the IR spectra is indicated by a square. The aperture sizes used for the precipitate and analytical-grade DZP were 100 μm × 100 μm and 30 μm × 30 μm, respectively. The y-axis of each spectrum has arbitrary units.Back to article page
