title: Dataset of glycerol analyzed using NMR and GCMS

description: This dataset includes raw and processed data on glycerol, obtained through Nuclear Magnetic Resonance (NMR) and Gas Chromatography-Mass Spectrometry (GCMS) analyses. The dataset is intended to analyze the purity of glycerol produced from animal and plant-based glycerol.NMR Data:Technique Used: Proton (1H) NMR and Carbon (13C) NMR.Instrumentation: Bruker NMR 500 with proton measurements at 500 MHz and 24°C to determine its carbon structure.Sample Preparation: Solvent used is deuterated methanolSpectral Data:Chemical Shifts: Values in ppm for prominent resonances.Coupling Constants: J-values for significant couplings.Integration Values: Relative integrals for proton environments.Processed Data: Standard glycerol NMR spectra (PNG).GCMS Data:Technique Used: Gas Chromatography coupled with Mass Spectrometry.Instrumentation: Agilent 7890B GC with an Agilent 5977A Series GC/MSD system. The column used was Agilent J&W DB-Wax UI (30 m 0.25 mm 0.25 µm). Helium was used as the carrier gas with an inlet temperature of 250 C in the split mode (20: 10). The GC oven started at 40 °C and was raised to 65°C at the rate of 20°C/min without holding. Then, it was raised to 250°C at the rate of 50°C/min. No solvent delay was detected. The mass spectrum was obtained by ionization and the detector temperature was set at 230 °C and operated in scan mode from 29-400 amu.Sample Preparation: Each sample was injected with a volume of 1 mL examined in triplicate.Chromatographic Data:Retention Times: 9.929 to 9.938s with single peak detected.Mass Spectral Data:Mass-to-Charge Ratios (m/z): m/z 61, m/z 43, m/z 44, m/z 45, m/z 29, m/z 15 and m/z 31Processed Data: Chromatogram of animal and plant-based glycerol (PNG).
