Detailed information
Summary Last years have been growing the interest in the quantitation of pharmaceuticals and drugs, called Emerging Organic Contaminants (EOPs), in drinking water or wastewater, in order to control the presence of these compounds and to avoid future problems on the people. LC/MS is the appropriate technique because of the selectivity, good sensitivity, linearity and robustness. Problems had begun when confirmation of target compounds must to be done and identification of unknown compounds is also needed. Mainly at very low concentrations, MRM ratios are not so consistent for confirmation. Hybrid QTrap MS/MS (QqLIT) systems allow to do that confirmation issues. "On-Line SPE" offer several features to improve the performance of the method: less sample volume, less timework required, better recoveries. Only 1 ml sample is needed to achieve the detection limit required.

Remarks This job shows a very rapid and effective method using all the most of the features of a QqLIT system to get very good sensitivity and identification capabilities. Using MRM transition to quantitate and MS/MS spectrum obtained with the Linear Ion Trap for identification purposes is possible to work with a low resolution system and found unknown compounds from a pre-target list.
