It was the reason for development of a new and better method of sample preparation, which uses microtome. Well-prepared samples analyzed by SEM and FTIR mapping allow to determine a solid dosage form formulation, excipient content and distribution of excipient and active pharmaceutical ingredient....
The successful appending of silane alkyl groups onto the zeolite crystals was verified via Fourier transform infrared (FTIR) spectro- scopy (Fig. 4a). The Pt@HieTS-1-C3 gives additional IR peaks at 2933, 2851, and 1387 cm−1, which correspond to the stretching vibration of -CH3 and -...

attenuated total reflection-Fourier transform infrared (ATR-FTIR) (PerkinElmer, Spectrum Two) and X-ray photoelectron spectroscopy (XPS; Thermo Fisher Scientific) were used to analyze the functional groups on the films. The surface morphology and elemental composition of all the samples were observed ...
Fourier transform infrared spectroscopy (FTIR) analysis The chemical interactions between the ingredients in the oleogel formulation (pumpkin seed oil, soy lecithin, beeswax, and bioactive compound extract) were assessed using FTIR analysis. The functional groups of the components during the scanning range...
FTIR spectra of excipients, physical mixture and formulation Full size image Drug Content The drug content was determined for the 3D-printed gummy formulations to evaluate the amount of each drug present in the formulation. Formulation F3 had drug content within the acceptable limits according to USP...
Fig. 1. XRD pattern of GO (a); XRD pattern of GO/γ-Fe2O3 (b); and FTIR spectra of GO, γ-Fe2O3, and GO/γ-Fe2O3(c). The FTIR spectrum of the GO sample exhibits bands of vibrational modes of CO at 1719 cm−1, of COH at 1417 cm−1 and CO at 1055 cm−1 (Fi...
The technique of Fourier transform infrared (FTIR) spectroscopy, in conjunction with new methods of sample presentation, has been used to study biopolymer ... M Arjmand,TD Spittler,RO Mumma - 《Journal of Agricultural & Food Chemistry》 被引量: 37发表: 1988年 [Solid/liquid interfacial in situ...
The preparation of solid polymer electrolyte Full size image 3Results and discussions Figure2a–c shows the FTIR spectra of PVA_xwt.%SiO2; the bands at the wavenumber range 3150–3450 cm−1indicate the O–H stretching vibration of hydroxyl groups. The area under the peak and its intensity ...
Similar protocol was followed for the preparation of lipid reconstituted ASR for DSC, FTIR, and UV-Vis measurements, except that ASR was expressed using non-isotopically labeled glucose and ammonium chloride. SSNMR detected H/D exchange experiments ...
