MILFORD, MA, Sept. 2, 2010 -- The United States Environmental Protection Agency (EPA) has published two rapid screening methods for chemical dispersants in seawaters using Waters® ACQUITY UPLC®/Quattro Premier™ XE (UPLC/MS/MS). These analytical procedures were developed by Dr. Lawrence Zintek, National Organic Methods Development Expert, and Dr. David Schroeder, US EPA Region 5 Chicago Regional Laboratory (CRL) in collaboration with Dr. Johnson Mathew, Region 6 Houston Laboratory.

These two methods specifically target the analysis of dipropylene glycol monobutyl ether (DPGBE), ethylene glycol monobutyl ether (EGBE), and dioctyl sulfosuccinate (DOSS) in seawater; three compounds used in the Gulf of Mexico in response to the oil leak.

"The key to these dispersant methods developed by EPA Region 5 Laboratory is the direct sample injection while meeting the water quality criteria goals," said Joe Romano, Senior Manager of Chemical Analysis for the Waters Division. "While the scientific community is just starting to understand the impact of the oil spill in the Gulf, what is clear is that preparing samples, such as seawater samples, may be the most challenging step in the analytical process. Direct injection of seawater into the UPLC/MS/MS system streamlines sample preparation and ensures analytical consistency from analytical run to analytical run. This rapid low level analysis also saves time and money."

The methods are available from the US EPA Region 5 Chicago Regional Laboratory by contacting Dr. Lawrence Zintek at [email protected].
