Abstract:

In typical flow-modulated GCxGC-MS, the GC flow must be split prior to introduction into the MS, because the pumping capacity of the MS can't handle the high flow rate.  Splitting GC flow increases the complexity of the measurement, and may be undesirable when maximum sensitivity is required.  Flow-modulated GCxGC was tested without flow splitting on a quadrupole MS that can accept a high flow rate.  Results detailing the effectiveness of the method will be presented, as well as its application to petroleum samples.
