Quantitative Determination of Pitavastatin in Tablets Using FTIR and RP-HPLC Analysis: A Comparative Study.

Background: Fourier Transform Infrared (FTIR) spectroscopy and reverse phase highperformance liquid chromatography, RP-HPLC analysis have been used for the quantitative determination of local l commercially available Pitavastatin products.

Methods: The FTIR method of analysis is not widely used in pharmaceutical quality control laboratories. This technique is non-destructive, reliable, precise, and efficient, and the samples can be prepared easily.

Wide angle X-ray diffraction patterns and 2D-correlation spectroscopy of crystallization in proton irradiated poly(ether ether ketone).

Proton irradiated poly (ether ether ketone) (PEEK) films were crystallized to different extents, and subsequently characterized by wide angle X-ray diffraction technique. The data were analyzed by two-dimensional correlation mapping (2D-CM), in particular: Generalized, hybrid and multiple perturbations correlation approaches. Two asynchronous correlation peaks at (19.
