The GC/MSD PAH analyzer is a turnkey system based on the 7890 Series GC and 5975C Series Single Quadrupole Mass Spectrometer and is suitable for use with a wide variety of environmental and food samples. The analyzer has undergone complete factory setup and chemical testing prior to shipment so that samples can be run on day one and significantly reduces method development and start-up time. Backflush, based on Capillary Flow Technology, is built-in to reduce overall cycle time and optimize uptime. Sample preparation is accomplished using a fast and simple Agilent QuEChERS PAH kit. The combination of QuEChERS and advanced GC/MS technologies reduces analysis time and improves detection limits.
