Detection and Identification of Gulf Oil Dispersants (COREXIT® 9527 and 9500) by GC/MS and LC/MS/MS

In this technical note Phenomenex highlight how GC/MS with Zebron™ ZB-WAXPLUS™ GC columns can be used to detect COREXIT 9527 directly from seawater, relevant in cases such as the recent oil spill in the Gulf of Mexico. To improve GC/MS stability, a cleanup procedure using the Strata™-X-A sorbent is used to virtually eliminate matrix interferences. The Kinetex® core-shell columns simultaneously detect both products at the low part per billion levels in seawater using LC/MS/MS. All solutions are optimized for high speed analysis and overall lab productivity.
