MDGC/GCMS Series

MDGC/GCMS Series

The complete separation and quantification of specific compounds can be difficult in samples that contain many compounds, such as petroleum products and fragrance products. Multi-Dimensional GC (MDGC) uses columns with different separation characteristics to achieve highly accurate separation of target components from such complex matrices.

Multi-Dimensional GC/GCMS System

The multi-dimensional GC/GCMS system uses two columns with different separation characteristics to achieve high-resolution analysis not possible with a conventional single column. Components insufficiently separated as they pass through the first column (1st column) are introduced ("heart-cut") into a second column of a different type (2nd column) to separate their analytes.

Outstanding retention time stability

Multi-Deans Switching
In the past, samples have been introduced to columns using the switching mechanism known as Deans-switching. However, this system results in such problems as a reduced recovery rate and fluctuations in the retention time.
The MDGC/GCMS Series system incorporates multi-Deans switching, a new mechanism that significantly reduces the likelihood of fluctuations in the retention times of eluted components, even if switching is performed several times.

Using the "MDGCsolution" MDGC control software, the flow rate conditions for both columns and the switching program can be set simply with mouse operations while viewing the chromatogram obtained with the 1st column.

Excellent Peak Picking Capability

One important feature of MDGCsolution is that it allows the switching settings to be performed while viewing the chromatogram. If you move the cursor near a peak to be heart-cut on the chromatogram and double-click, the switching is set in units of 0.01 minutes. Because operation is this simple, hardly any time is required when performing multiple switching or when creating multiple methods with different switching timings. It is also possible to create a method during analysis using the Offline Editor menus.

A Wide Variety of Optional Systems

In addition to GCMS, various other detectors, such as an FID or FPD, can be used with the MDGC/GCMS series. For example, a headspace sampler and thermal desorption system can be connected and controlled as a pretreatment system. When not using the MDGC/GCMS series as an MDGC system, it is possible to use the GC and GCMS components as independent systems by changing the column and detector connections.

Ease of Maintenance

GC Oven Interior

The switching element is located at the top of the front edge of the GC oven. Column replacement and connection to the detector or pretreatment unit are easy. The column connectors contain highly heat-resistant stainless-steel ferrules to eliminate the need for retightening and the danger of seizing associated with conventional Vespel ferrules. Both connection and maintenance are easy.
