Multimode Inlet (MMI) for GC
Multimode Inlet
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.
- GC Inlets
Product Details
- 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

Fast Residual Solvents and Terpenes Analyses in Cannabis and Hemp Products
New methods have been developed for the analysis of residual solvents and terpenes in cannabis and hemp products using a single 7697A Headspace Sampler/Intuvo 9000 GC/5977B MSD system. Results are approximately 50% and 30% faster for the solvents and terpenes, respectively, compared to the original applications. The single platform-two analyses approach has been successfully implemented in labs across North America.
