The document compares the performance of Agilent Technologies' new series of instruments, the 7890 Series GC and 5975 Series MSD, to the previous versions, the 6890 Series GC and the 5973 Series MSD. Performance is shown to be fully equivalent in test comparisons using a 16-component polynuclear aromatic hydrocarbon (PAH) sample. The document also discusses the reliable transfer of existing methods from the 6890/5973 system to the new 7890/5975 system.
Agilent Technologies introduced the 7890 Series GC and 5975 Series MSD to replace the 6890 and 5973 series. This document validates that performance is fully equivalent between the old and new systems using a 16-component polynuclear aromatic hydrocarbon (PAH) sample.
The study compares system configurations, including the Agilent 6890A GC with a 5973N MSD against a production prototype 7890A GC with a 5975B MSD. Results show that methods can be migrated with high confidence, achieving excellent reproducibility and calibration characteristics without needing redevelopment.
| Carrier gas | He, constant pressure mode, nominal 13 psig |

| Inlet temperature | 300 °C |
| Source temperature | 230 °C |
| Quad temperature | 150 °C |
| Transfer line temperature | 280 °C |
Yes, methods can be migrated to the new systems with high confidence that performance will be equivalent or better.
No, the new systems easily reproduced method characteristics without the need for method redevelopment.
