The Benefits of Incorporating GC/QQQ into Pesticide Analysis Methods

9instrument uses two of the hyperbolic gold-plated quartz quadrupoles that have proved to be so stable and rugged in the 5973 and 5975 series MSDs. The ability to heat them up to 200 oC means that cleaning is rarely, if ever, required. The collision cell is a shorter version of the hexapole used in Agilent’s 6460 LC/QQQ instrument. Agilent’s innovative use of helium quenching in the collision cell significantly reduces background noise and enhances the signal-tonoise ratio of the instrument. Finally, the 7000A is fully integrated to the 7890A GC and benefits from column backflushing and other capillary flow techniques.4 The control software combines the familiar instrument control portion of Agilent’s GC‐MS ChemStation with the powerful MassHunter data analysis package that is now available on Agilent’s LC-TOF, LC-Q-TOF, and LC/QQQ instruments.
