LC-MS analysis
A six-page technical report titled “Analysis of Artificial Colorants by Ultra-Fast Liquid Chromatography – Mass Spectrometry” is available from Shimadzu Scientific Instruments Inc. Downloadable from the company Web site, the publication describes analysis, retention time and peak repeatability using Shimadzu’s liquid chromatograph ion trap time-of-flight mass spectrometer, Prominence UFLC, and high-speed Shim-pack XR-ODS columns. Research determined that the method provides shorter analysis time in comparison with the conventional liquid chromatography method.
