On-line SPE Enrichment of Trace Organic Contaminants in Water and Juices
30 Jul 2014
This application note describes an on-line SPE method for the identification and quantitation of trace levels of organic contaminants (pharmaceuticals and pesticides) in environmental waters and juices using the Agilent Flex Cube solution followed by detection with triple quadrupole mass spectrometry. A small volume (900 µL) was preconcentrated on polymeric cartridges. Analytical performance data of the on-line SPE system for linearity, recovery, and detection limits in real samples is shown and discussed. Recoveries varied from 41 to 115%. Method detection limits ranged from 1 to 500 ng/L.
