A new tool for the rapid analysis of organic impurities in raw sugar
By Papageorgiou, J; Doherty, WOS; Walker, B; Edye, LA
A simple procedure for the isolation and separation of organic impurities from raw sugar has been described. The capability of high performance liquid chromatography connected in series to an ultravoilet detector and mass spectrometer (HPLC-UV-MS) to identify and characterise organic impurities has been assessed. Organic impurities were separated on an HPLC column and then detected, and in some cases identified, using a UV absorption detector and mass spectrometer (MS). Numerous organic impurities were separated while the run time for analysis was less than 60 min. As a result of this work, chemical structures of eight organic impurities present in raw sugar were tentatively identified.
