Configuring the GC/MS System for <strong>Pesticide</strong> Analysis<br />
TSQ Quantum GC Mass Spectrometer<br />
The TSQ Quantum GC mass spectrometer ships with the recommended configuration for pesticide analysis. It is equipped for easy ion volume exchange.<br />
The method settings for the TSQ Quantum GC will provide good results for all listed compounds. Adjustments can be made if the compound list changes or<br />
additional sensitivity is required.<br />
