Direct Sample Inlet Unit

Direct sample injection (DI) is a method in which a sample is injected directly into the ion source without passing through the gas chromatograph (GC). This is an effective method for measuring the mass spectra of synthetic compounds, and can be used easily for the usual GC-MS configuration. By using this in combination with Smart EI/CI ion source, EI and CI mass spectra can easily be collected.

• Available for analysis of resins and material-related samples (maximum temperature 500°C).
• DI analysis is available without removing column in GC oven.
• CI and NCI are available as well as EI for DI.
• Simple operation.
