Advanced
Flow Technology Series
Multi Dimensional Gas
Chromatograph Systems
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.
Superior Intuitive
Operability
MDGCsolution Software
MDGC Analysis Conditions Display Window
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
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.
