Multimode Inlet (MMI) for GC
Multimode Inlet
The Multimode Inlet (MMI) combines the flexibility of a standard Agilent split/splitless inlet with the capabilities of a programmable temperature vaporizer (PTV) inlet. It can perform large-volume injections for trace analysis, cool injections for improved signal response, pulsed injections that eliminate inlet liner overload and backflash, and direct injection.
The injection technique that is used for a method can be tailored to the compounds in your samples. Using the MMI, the gas chromatograph can meet current analytical needs and provide flexibility to meet future requirements.

Product Details
Features
- Large volume injection (LVI) capabilities
- Agilent Turn Top inlet for easier maintenance
- Temperature range of -160 ºC to 450 ºC
- Agilent Solvent Elimination Calculator assists user in setting large-volume injection parameters
- Cooling options include air, liquid nitrogen, and liquid carbon dioxide
- Electronic septum purge flow control to eliminate ghost peaks
- Compatible with Merlin Microseal for GC
- Injection modes include split, pulsed split, splitless, pulsed splitless, solvent vent, direct, and sleep
- Split mode is generally used for major component analysis
- Pulsed split mode is like split mode, but with a pressure pulse applied to the inlet during sample introduction to speed the transfer of material to the column
- Splitless mode is used for trace analysis
- Pulsed splitless mode allows for a pressure pulse during sample introduction
- Solvent vent mode is used for large-volume injection; single or multiple injections can be made for each run
- Direct mode allows for a direct forward pressure of carrier gas through the column with the split vent closed
- Sleep mode is used for creating sleep methods, or if all gas needs to flow onto the column
