These preliminary results from this study demonstrate that the TSQ 9000 GC-MS/MS system configured with the AEI source provides an unmatched level of routine-grade robustness and represents a reliable analytical platform for routine high-throughput laboratories. Taken together, the experiments demonstrate:
- Ion flux stability over 900 sequential matrix injections, equivalent to one month's continuous data acquisition (33 samples per day for 27 consecutive days) and displaying consistent ion ratio response throughout.
- Relative standard deviations of <20% for over 90% of the 150 pesticides at a concentration of 10 ppb [µg/kg] using a single capillary column and no source maintenance.
- The SmartTune feature for fast, simple and reliable tuning for both the ExtractaBrite and AEI sources on both the ISQ 7000 and TSQ 9000 platforms, ensuring consistent performance with an easy interface.
