The IR spectra of bulk polymers, drug and ASDs were collected in the attenuated total reflectance (ATR) mode using a Bruker Vertex 70 FTIR spectrometer (Billerica, MA) equipped with a Golden Gate ATR accessory (Specac, Orpington, Kent, UK). The spectrum of each sample was the average of triplicate runs of 32 scans and a resolution of 4 cm−1. The data were analyzed using OPUS software (version 7.2, Bruker, Billerica, MA).

A FTIR spectrometer (Tensor 27; Bruker Optics Ltd., Coventry, UK) with a Specac™ multi-bounce (25 reflection, 45º, refractive index of 2.40) ATR accessory (Specac Ltd., Orpington, UK) -ZnSe (7.2 × 1.0 cm 2 ), was used to collect the reference spectra for the solid form of DF Na (ethanolic paste), DF Na in PG (200 mg/mL) and DMSO (100 mg/mL). The ethanol paste of DF Na was prepared by mixing a minimal amount of ethanol with DF Na powder. This paste was then spread evenly on the ZnSe crystal and allowed to dry for about half an hour before collecting spectra [7] .
For analysis of solutions, an aluminum slab was used to form a reservoir using vacuum grease. For each sample 32 scans were collected with a resolution of 4 cm -1 in the range of 4000 cm -1 to 600 cm -1 . The spectra collected were analysed using Opus software version 6.0 (Bruker Optics Ltd., Coventry, UK) and OriginPro 9.0.0 (OriginLab Corp., Northampton, MA, US).

Fourier-transform infrared (FTIR) measurements were carried out in attenuated total reflectance (ATR) mode. The infrared spectra of the samples were collected using a Bruker IFS 66/S spectrophotometer (Bruker Optics Ltd., UK), fitted with a Golden Gate ATR accessory from Specac Ltd. (UK). Measurements were carried out over a spectral range of 4,000 to 550 cm -1 with a total of 16 scans acquired at a resolution of 4 cm -1 .

ATR FT‐IR spectra were recorded on a Perkin‐Elmer Spectrum GX spectrometer. The ATR accessory (supplied by Specac Ltd., UK) contained a diamond crystal. A total of 16 scans for each sample were taken with a resolution of 4 cm−1. All spectra were recorded at 21 °C over the wavelength interval between 4000 and 650 cm−1.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
