Multimode Inlet for Gas Chromatograph-Mass


High-Performance Multimode Inlet

A Next-Generation Inlet Accommodating a Variety of Sample Forms


Equipped with injection modes capable of accommodating a wide range of sample forms, the OPTIC-4 is the ultimate inlet in GC-MS sample injection systems. Attaching the OPTIC-4 to the GCMS-QP2010 Ultra draws out its very best performance.

Injection Flow(wmv13.3MB)


Excellent Basic Performance of the OPTIC-4


A Diversity of Injection Modes Is Available
In addition to split/splitless injection modes, the following modes can all be achieved with a single inlet.


Capable of High-Speed 60 ℃/sec Heating


By adopting a direct heating method, the OPTIC-4 achieves a maximum heating speed of ℃/sec. As a result, chromatogram peak spread in thermal decomposition analysis is suppressed to a minimum.



Ideal Flow Channels


The OPTIC-4 does not use switching valves or transfer lines. Because of this, compound adsorption due to cold spots can be minimized. This is optimal for the analysis of compounds with a high boiling point, as well as adsorptive and degradable compounds.


DMI (Difficult Matrix Introduction) Mode Simplifies Pretreatment

MDI Mode

DMI is a method of analyzing samples by placing a microvial containing the sample inside a liner, and then heating the liner at the inlet. By adjusting the temperature of the inlet, nonvolatile impurities can be left behind in the microvial, enabling GC-MS measurements with simplified pretreatment. 


Analysis of Shampoo via DMI Mode


An undiluted sample of shampoo was placed directly into a microvial, and was analyzed in DMI mode. It was possible to selectively analyze the volatile compounds.
