Direct Inlet (DIP)
This supplement for the Agilent detectors MSD 5975 and 5977, Triple Quadrupole Mass Spectrometer 7000/7000D/7010B, as well as the 7200 GC-Q-TOF enables the direct acquisition of mass spectra without uncoupling the GC/MS interface. Additionally we offer the Direct Inlet Probe system also for GC/MS systems by Shimadzu and Leco. A push rod is used to insert the sample into the vacuum of the ion source to record the mass spectrum:
- The tip of the push rod keeps the inlay with the sample (either for liquid or solid samples)
- An externally controlled valving and pumping system permits the sample to enter the MSD vacuum system with minimal air introduced into the system.
- When the push rod is fully injected, the probe tip is heated (programmable at ramp rates).
- Acquisition and evaluation of the spectra (EI or CI mode) is done by the Agilent MS software.
