Spectrum 400 ft ir fir spectrometer

The characterization of the MWCNT structure was analyzed using field-emission scanning electron microscope (FE-SEM, SU 8010, Hitachi). Energy dispersive x-ray spectrum (EDX) analysis was performed to quantify the elements of the sample which was also verified by elemental analysis on a CHNS–O elemental analyser (Flash 2000, Thermo Scientific). FTIR spectra were carried out on a Spectrum 400 FT-IR/FIR spectrometer (Perkin Elmer). Agglomeration studies were performed using visual observation after dispersing 1 mg of the various MWCNTs in 10 ml of MiliQ water and in 10 ml of DMEM (10 % FBS supplemented) to replicate the culture medium conditions and leaving them undisturbed for 7 days. Subsequently, the aqueous MWCNT samples after bath sonication were subjected to zeta potential analysis for estimation of charge to size ratio of the dispersed/dissolved nanoparticles.

Spectrum 400 FT-IR/FIR Spectrometer, Perkin Elmer, USA was used for FTIR Study of THC, GMS, their physical mixture, and the lyophilized optimized THC-SLN using KBr pellet system. The absorption bands with characteristic peaks were obtained in the range of 4000–650 cm⁻¹.
