Analysis of Organic Micropollutants by HPLCThe potential of HPLC as analytical method for the analysis of nonvolatile organic compounds in complex mixtures is discussed. The state of art to optimize the analysis via the number of theoretical plates of the separation column,via multicolumn operation and by applying selective detection is reviewed.

David A. Vuletich,Juliette T. J. Lecomted by methods involving shaking with solvents or ultrasonic agitation, and steam distillation. The ultrasonic agitation gave similar results to shaking but showed considerable savings in time. Steam distillation gave cleaner extracts but with lower recoveries and it did not remove the heavier PAR fro
