Magnetic resonance imaging drawbacks

TLC remains one of the most widely used techniques for a simple and rapid qualitative separation. The combination of TLC with spectroscopic detection techniques, such as FTIR or nuclear magnetic resonance (NMR), is a very attractive approach to analyze polymer additives. Infrared microscopy is a powerful technique that combines the imaging capabUities of optical microscopy with the chemical analysis abilities of infrared spectroscopy. FTIR microscopy allows obtaining of infrared spectra from microsized samples. Offline TLC-FTIR microscopy was used to analyze a variety of commercial antioxidants and light stabilizers. Transferring operation and identification procedure by FTIR takes about 20 min. However, the main drawbacks of TLC-FTIR are that TLC is a time-consuming technique and usually needs solvent mixtures, which makes TLC environmentally unsound, analytes must be transferred for FTIR analysis, and TLC-FTIR cannot be used for quantifying purposes. [Pg.1865]
