Pesticide Residue Analysis of Sugar

摘要

1. Sugar can be handled conveniently as a matrix using solid phase extraction (SPE). Using less solvent in SPE as against liquid-liquid extraction (LLE) helps improve the recovery, and reduces losses due to minimal use of glassware, solvents and manual operations. 2. The use of Mass Spectrometric detection greatly reduces the ambiguity associated with analysis of sugar. Sugar having a high background containing various plant derivatives, organic acids, phenolic compounds and sterols detection of trace level pesticides from such background is a formidable challenge in the absence of a mass detector. 3. The use of a mass detector greatly reduces the risk of misinterpretation of the background as a potential residual analyte. 4. The use of ionization techniques like SIS (Selected Ion Storage), MS/MS~n , MRM (Multi Residue Monitoring) helps resolve the problems associates with excessive background, final confirmation and co-eluting compounds respectively.
