Shimadzu Scientific Instruments has released technical reports for liquid chromatography mass spectrometry (LC MS).
The reports include research on artificial colourants, polymer additives and nutraceuticals.
'Analysis of Artificial Colourants by Ultra-fast LC MS' describes analysis, retention time and peak repeatability using Shimadzu's LCMS-IT-Tof mass spectrometer, Prominence UFLC, and high-speed Shim-pack XR-ODS columns.
Research determined that this method shortens analysis time to one-sixth of that obtained using conventional LC, and compound identification could be conducted with greater certainty.
Shimadzu also researched the 'Identification of Unknown Polymer Additives by LCMS-IT-Tof'.
This technique, which uses MSn measurements and accurate mass, helps to identify commercial additives, including ultraviolet light absorbing agents and stabilisation agents.
In addition, Shimadzu studied 'Natural Product Analysis Using LCMS-IT-Tof', due to the rising popularity of remedies consisting of nutraceuticals that are found in foods, roots and herbs.
With LCMS-IT-Tof, researchers obtained chemical and structural information by using the fragmentation power of the ion trap, and the high resolution and accuracy of the time-of-flight mass spectrometer.
