FTIR assay method for UV inactive drug carisoprodol and identification of degradants by RP-HPLC and ESI-MS

Preparation of Lauroyl Grafted Alginate-Psyllium Husk Gel Composite Film with Enhanced Physicochemical, Mechanical and Antimicrobial Properties

“…This is also known to be common problem for substituted polysacharides for the determination of degree of substitution using NMR 16 . However, the complete disappearance of the –OH peak at 3402 cm −1 in the FTIR spectrum of the glycolipid suggested the total substitution of lauroyl group on alginate 17 , 18 .…”

Molecularly imprinted polymer-based dispersive solid-phase extraction for the selective determination of carisoprodol in biological and pharmaceutical samples

“…Several procedures have been published for the identification of CSP including liquid chromatography combined with mass spectrometry (LC-MS), 14,15 gas chromatography coupled with mass spectrometry (GC-MS), 16 reversed-phase high-performance liquid chromatography (RP-HPLC), and electro-spray ionization with mass spectrometry (ESI-MS). 17 In addition, the solid-phase extraction (SPE) method is utilized for sample pre-concentration, extraction, and clean-up before most of the above-mentioned analytical techniques. 18 Although the first experiment-based applications of SPE were reported fifty years ago, it was only in the middle of the 70s that this technique was applied to analytical tasks.…”
