Authentication of cinnamon spice samples using FT-IR spectroscopy and chemometric classification

Classification of frankfurters by FT-Raman spectroscopy and chemometric methods.

Frankfurters are widely consumed all over the world, and the production requires a wide range of meat and non-meat ingredients. Due to these characteristics, frankfurters are products that can be easily adulterated with lower value meats, and the presence of undeclared species. Adulterations are often still difficult to detect, due the fact that the adulterant components are usually very simila...

FT-IR Photoacoustic Spectroscopy

Classification of Bacteria Using FT-IR

The classification of bacteria is generally based on the morphology and biochemical reactions of the bacteria. However, these measurements are time consuming, and require training and expertise. Infrared (IR) spectroscopic measurements of bacteria followed by a formal chemometrics analysis could offer advantages of speed and consistency. Such an analysis was first tried in the late 1950s, with ...

FT-IR Spectroscopy in Medicine

Infrared spectroscopy has been widely applied for the characterisation of various substances. Due to its sensitivity to the chemical information and architecture of the molecule, infrared spectroscopy can play an important role in new applications such as in the life-science field and not only in the traditional fields of physics and chemistry. Spectroscopic techniques are simple, reproducible,...

Chemometric analysis of Nicotiana tabacum FAME’s using GC/MS, FT IR and NMR spectroscopic studies

Nicotiana tabacum commonly known as Tobacco plant which has broad application over soap, paint and cigar industries was now investigated for biodiesel production. Nicotiana tabacum seeds were one of the prominent sources for non-edible oil. Oil from Tobacco seeds were expelled with Soxhlet extraction apparatus using n-hexane as extraction solvent. Two stage trans-esterification has been adopted...
